Guest User's in Presence Channel

How do I allow guest user, join in Laravel Reverb Presence Channel? It seems like I can't override the '/broadcasting/auth' route.

I tried overriding it using a middleware, but it doesn't work.

// api.php
Route::post('/broadcasting/auth', function (Request $request) {
    if (Auth::check) {
        return Broadcast::auth($request);
    }
    return response()->json(['message' => 'Unauthorized'], 403);
})->middleware('authenticateGuest');

// AuthenticateGuest Middleware
public function handle(Request $request, Closure $next): Response
{
  if (! Auth::check()) {
      $user = User::factory(1)->make();

      Auth::login($user);
  }

    return $next($request);
 }
