Service worker 'notificationclick' event not firing on notification click (Firebase FCM)

I am trying to implement push notifications for web.I have succesfully managed to display background notification. But on clicking it, the notification does not open the window or link I want.Rather, the function just does not fire.

Below is the code of my firebase-messanging-sw.js file.

self.addEventListener('notificationclick', function(event) {
  console.log('[firebase-messaging-sw.js] Notification click received.');

event.notification.close();


const path = event.notification?.data?.url || '/';
// const fullUrl = 'http://localhost:3000' + path;

event.waitUntil(
  clients.openWindow(path)
    .catch(err => console.error('Error opening window:', err))
);
});



importScripts('https://www.gstatic.com/firebasejs/8.4.1/firebase- app.js');
importScripts('https://www.gstatic.com/firebasejs/8.4.1/firebase- messaging.js');


const firebaseConfig = {
  apiKey: "***",
  authDomain: "***",
  projectId: "***",
  storageBucket: "***",
  messagingSenderId: "***",
  appId: "***",
  measurementId: "***"
};

firebase.initializeApp(firebaseConfig);
const messaging = firebase.messaging();


messaging.onBackgroundMessage(function(payload) {
  console.log('[firebase-messaging-sw.js] Received background  message ', payload);

const notificationTitle = payload.data?.title || 'New Notification';
const notificationOptions = {
  body: payload.data?.body || 'You have a new message',
  icon: '/firebase-logo.png',
  badge: '/badge-icon.png',
  data: {
    url: payload.data?.url || '/',
  },
  actions: [
    {
      action: 'open',
      title: 'Open App'
    }
  ]
};

self.registration.showNotification(notificationTitle, notificationOptions);
});

The 'notification click' function is just not firing.Nothing gets printed on the console when I click on the notification. I have tried everything mentioned on internet-

• tried opening a different link(youtube.com)
• tried moving the 'notification click' function on top
• checked that service worker is registered and running.

please tell me any fix for this or anyhting that I may have missed.
