Django - How to hide Server [HTTP Response header] parameter in middleware file?

In my Django application, the following settings ensure that the response headers have the standard key-value pairs enabled.

However, the 'Server' name and version information is still visible by default which needs to be hidden (exposed server name and version is an OWASP vulnerability).

middleware.py

class MyAppMiddleware:

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        response['X-XSS-Protection'] = "1; mode=block"
        return response


class RemoveHeaders(object):           # this method invocation throws error
    def process_response(self, request, response):
        response['Server'] = ''
        return response

Also as suggested in other posts, this middleware.py is declared in the first order of middlewares in settings.py:

MIDDLEWARE = [
    'MyApp.middleware.RemoveHeaders',
    'MyApp.middleware.MyAppMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

The RemoveHeaders() method throws error: TypeError: RemoveHeaders() takes no arguments. This is because I am unsure which object is being passed to this method.

Update: importing the following worked for me.

from django.utils.deprecation import MiddlewareMixin


# class to import in RemoveHeaders--

class RemoveHeaders(MiddlewareMixin):
     # rest of the code
