PrivateChannel 403 error Laravel Echo Pusher Laravel Websockets local setup

I am getting a 403 on broadcasting/auth route.

I am using Laravel websockets package for web sockets and I have the below setup

- Backend Laravel server ( on port 8000 )
- Laravel Websockets Server ( laravel is running on 8001 and websocket server on 6001 )
- Standalone Ionic React app ( on port 8100)

Now everything works when I am trying Public Channel but when I try Private Channel it fails.

in the above screenshot of Laravel sockets dashboard I can see connection made as this is the same socketId which went with the request.

I am using Laravel Sanctum for Authentication.

PFB :- my client side code

const headers = {
    'Content-Type': 'application/json',
    Authorization: window.localStorage.getItem('token')
      ? `Bearer ${window.localStorage.getItem('token')}`
      : '',
    'Access-Control-Allow-Credentials': true,
  };
  const options = {
    broadcaster: 'pusher',
    key: 'abcsock',
    authEndpoint: 'http://localhost:8001/api/broadcasting/auth',
    authorizer: (channel, options) => {
      return {
        authorize: (socketId, callback) => {
          axios
            .post(
              'http://localhost:8001/api/broadcasting/auth',
              {
                socket_id: socketId,
                channel_name: channel.name,
              },
              { headers, withCredentials: true }
            )
            .then((response) => {
              callback(false, response.data);
            })
            .catch((error) => {
              callback(true, error);
            });
        },
      };
    },
    wsHost: '127.0.0.1',
    wsPort: 6001,
    encrypted: true,
    disableStats: true,
    enabledTransports: ['ws', 'wss'],
    forceTLS: false,
  };

    public function broadcastOn()

channels.php

<?php

use Illuminate\Support\Facades\Broadcast;

Broadcast::channel('Notifications.{id}', function ($user, $id) {
    return (int) $user->id === (int) $id;
}, ['guards' => ['sanctum']]);

I have attached whatever I felt was sufficient to explain the issue and for you to troubleshoot but if you need anything more please ask.

Any help will be appreciated
