Django App not returning csrf token on get response.cookie consistently

Question

Given I have this GET view:

class PublicKeyView(View):
    def get(self, request):
        # Ensure a session ID is available
        if not request.session.session_key:
            request.session.save()

        session_id = request.session.session_key

        private_key, public_key = RSAKeyManager.get_keys(session_id)
        if not private_key or not public_key:
            # Keys are generated as bytes, so decode them before storing
            private_key, public_key = RSAKeyManager.generate_keys()
            RSAKeyManager.store_keys(session_id, private_key.decode('utf-8'), public_key.decode('utf-8'))


        if isinstance(public_key, bytes):
            public_key = public_key.decode('utf-8')
        print(public_key)
        # public_key = public_key.replace('\n', '')
        # Return the public key and session ID
        return JsonResponse({"session_id": session_id, "public_key": public_key}, status=200)

If I start a localhost server, and request GET for that view, it include in response.cookies CSRFToken

But if I do the same exact request to the app, but via host, it does not include the token, and I cannot understand why

Isn't the logic for CSRF to sent token via GET, use that received token to do POST requests?
