Answer 1

I am Posting this answer, For every one who might face the problem no-days. I am using laravel 7 and beyondcode/laravel-websockets. As I dig in the source code specifying midllewares in BoradcastServiceProvider.php will not work. The only way to define a guard for a channel is by specifying options for the channel:

 Broadcast::channel('messaging.organ.{id}', function ($organ , $id) {
    return $organ->id == $id && get_class($organ) === "App\Organization";
} , ['guards' => ['organ']]);

Reason: because I am using beyondcode/laravel-websockets so I dig in src/Illuminate/Broadcasting/Broadcasters/PusherBroadcaster.php and in this file the retrieveUser method will get the user. in this file if an option for the channel is provided the user in the specified guards will be returned. you can define one or multiple guards, however it will only returns one user who is logged in as a guard that comes first in the array.

    protected function retrieveUser($request, $channel)
{
    $options = $this->retrieveChannelOptions($channel);

    $guards = $options['guards'] ?? null;

    if (is_null($guards)) {
        return $request->user();
    }

    foreach (Arr::wrap($guards) as $guard) {
        if ($user = $request->user($guard)) {
            return $user;
        }
    }
}

Try changing in BroadcastServiceProvider file app\Providers\BroadcastServiceProvider.php

Different broadcast auth end point for each guards

public function boot()
{
   //Broadcast::routes();
   //match any of the 3 auth guards
   Broadcast::routes(['middleware' => ['web','auth:admins,designers,customers']]);
   require base_path('routes/channels.php');
}

Now in channels.php

Broadcast::channel('admins.channel.{id}', function ($model, $id) {
      return $model->id === $id && get_class($model) === 'App\Admin';
});

Broadcast::channel('designers.channel.{id}', function ($model, $id) {
      return $model->id === $id && get_class($model) === 'App\Designer';
});

Broadcast::channel('customers.channel.{id}', function ($model, $id) {
      return $model->id === $id && get_class($model) === 'App\Customer';
});
