Laravel Multi-auth check if user logged in and hide/show navigation tab

I am using the Laravel multi-auth for multiple users. I have frontend controller for the public access where no login is required. I want to check there if the user is logged in. If so I want to hide Login nav and show Home/Dashboard nav link which on click should redirect users to his dashboard. How can I check this in front-end controller/view? Any help is appreciated. Thanks in advance.

I have following guards:

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'token',
        'provider' => 'users',
    ],

    'admin' => [
        'driver' => 'session',
        'provider' => 'admins',
    ],

    'university' => [
        'driver' => 'session',
        'provider' => 'universities',
    ],

    'school' => [
        'driver' => 'session',
        'provider' => 'schools',
    ],

    'student' => [
        'driver' => 'session',
        'provider' => 'students',
    ],
],

Model:

    <?php

namespace Modules\Student\Http\Models;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Student extends Authenticatable
{
    use Notifiable;

    protected $guard = 'student';

    protected $fillable = ['first_name', 'last_name', 'email', 'password', 'remember_token'];

    public function applications()
    {
        return $this->hasMany("Modules\Student\Http\Models\Application", 'student_id');
    }

    public function languages()
    {
        return $this->hasMany("Modules\Student\Http\Models\StudentLanguage", 'student_id');
    }

    public function certificates()
    {
        return $this->hasMany("Modules\Student\Http\Models\StudentCertificate", 'student_id');
    }

    public function educations()
    {
        return $this->hasMany("Modules\Student\Http\Models\StudentEducation", 'student_id');
    }
}

Controller:

    <?php
namespace Modules\Student\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Http\Response;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use Modules\Admin\Http\Models\Country;

class StudentController extends Controller
{
    protected $redirectTo = '/student';

    public function __construct()
    {
        $this->middleware('auth:student');
    }

    public function index()
    {
       return view('student::dashboard');
    }

    public function profileForm()
    {
        $countries = Country::get(['id', 'country_name'])->toArray();
        $student = Student::with('languages')
            ->with('certificates')
            ->with('educations')
            ->with('educations.country')
            ->with('ducuments')
            ->find(Auth::User()->id);
        $student->countries = $countries;
        $student->docsGroup = $student->ducuments->groupBy('doc_type');
        return view('student::student_profile')
            ->withStudent($student);
    }

    public function deleteEducation($id)
    {
        $language = StudentEducation::find($id);
        if($language->delete()){
            return 'success';
        }
    }

    public function addCertificate(Request $request)
    {
        $this->validate($request, [
            'certificate_name'            => 'required',
            'certificate_score'            => 'required',
        ]);

        $certificate = new StudentCertificate();
        $certificate->student_id           = Auth::id();
        $certificate->certificate_name        = $request->certificate_name;
        $certificate->score                   = $request->certificate_score;
        if($certificate->save()){
            Session::flash('success', 'New certificate added successfully!');
            return redirect()->route('student.profile');
        };
        Session::flash('success', 'Some error occured while addeding certificate!');
        return redirect()->back()
            ->withInput()->with('tab', ['basic_info']);;
    }
}

And this is my controller where I want to check if any student/admin.. logged in or not:

use Modules\Admin\Http\Models\Country;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Session;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Auth;

{
//    public function __construct()

    public static function GetSearchAttributes()
    {
        $country_ids = University::where([
            ['status', '=', 'active'],
            ['id', '>', '0']
        ])
            ->get(['country_id'])
            ->pluck('country_id')
            ->toArray();

        $countries = Country::orderBy('country_name', 'asc')
            ->whereIn('id', $country_ids)
            ->get(['id', 'country_name'])

            ->toArray();

        $searchAttr['countries'] = $countries;
        $searchAttr['categories'] = $categories;
        $searchAttr['degrees'] = $degrees;
        $searchAttr = (object) $searchAttr;
        return $searchAttr;
    }

    /**
     * Display a listing of the resource.
     * @return Response
     */
    public function index()
    {
        $logos = University::orderBy('id', 'ASC')
            ->where([
                ['status', '=', 'active']
            ])
            ->limit(8)
            ->get();
        return view('student::index')->withLogos($logos);
    }
