Laravel Broadcasting не возвращает результатов

Пытаюсь создать real-time уведомления используя Laravel Echo и Pusher, но не получаю никаких результатов. Пользуюсь своим authentication middleware-ом, поэтому изменил файл BroadcastServiceProvider.php файл, передал атрибут, как указан в документации. Ниже мои файлы и код.

FriendRequest Event

<?php
namespace App\Events;
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;
use App\Users;
use App\Friend_requests;
class FriendRequest implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
    public $user;
    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($user)
    {
        $this->user = $user;
    }
    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('notification');
    }
}

routes/channels.php

<?php
/*

| Here you may register all of the event broadcasting channels that your
| application supports. The given channel authorization callbacks are
| used to check if an authenticated user can listen to the channel.

*/
Broadcast::channel('App.User.{id}', function ($user, $id) {
    return (int) $user->id === (int) $id;
});
Broadcast::channel('notification', function($user){
     return true;
});

app/Providers/BroadcastServiceProvider.php

<?php
namespace App\Providers;
use Illuminate\Support\Facades\Broadcast;
use Illuminate\Support\ServiceProvider;
class BroadcastServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Broadcast::routes(['middleware' => ['authorized']]);
        require base_path('routes/channels.php');
    }
}

bootstrap.js

import Echo from 'laravel-echo';
window.Pusher = require('pusher-js');
window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    encrypted: true,
});
window.Echo.private('notification')
    .listen("FriendRequest", (e)=>{
        console.log(e);
    });
    console.log("Laravel Echo");
