Pusher debug console return nothing when call event in laravel

Hi i make a simple event and call that event but Pusher debug console does not show anything here it is my event

<?php

namespace App\Evenets;

use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;

class MyEvent implements ShouldBroadcast
{
  use Dispatchable, InteractsWithSockets, SerializesModels;

  public $message;

  public function __construct($message)
  {
      $this->message = $message;
  }

  public function broadcastOn()
  {
      return ['student-notification'];
  }

  public function broadcastAs()
  {
      return 'student-notification-event';
  }
}

here .env pusher

BROADCAST_DRIVER=pusher
PUSHER_APP_ID=1459312
PUSHER_APP_KEY=f79f6e1a7efa759a16c3
PUSHER_APP_SECRET=8a676c825e5861236977
PUSHER_APP_CLUSTER=ap2

also uncomment EventServiceProvider in app.php here call event in call back route

Route::get('event',function(){
    event(new MyEvent('hello world'));
});

Thanks for any help
