http://localhost:8000/broadcasting/auth 403 Forbidden using laravel - php

Question

I want to do a real time chat, with websocket/pusher.
Installed laravel websockets by following the command: composer require beyondcode/laravel-websockets
Publish it by using: php artisan vendor:publish --provider="BeyondCode\LaravelWebSockets\WebSocketsServiceProvider" --tag="migrations"
php artisan migrate
php artisan vendor:publish --provider="BeyondCode\LaravelWebSockets\WebSocketsServiceProvider" --tag="config" (I configure file config/websocket.php)
Installed laravel pusher: composer require pusher/pusher-php-server "~3.0"
Uncommented App\Providers\BroadcastServiceProvider::class in config/app.php
Created a ChatEvent event
Launched websockets server by: php artisan websockets:serve
Opened link http://localhost/jwtchat/public/laravel-websockets then connect and everything works fine
I run php artisan tinker:
event(new App\Events\ChatEvent('hello'))
It works very well, but when I try http://localhost/jwtchat/public/broadcasting/auth in postman, it gives me 403 Forbidden error.
in payload it return me:
socket_id: 726245173.481815034
channel_name: presence-chat
