Laravel - Events - Manually Registering Events

Typically, events should be registered via the EventServiceProvider $listen array; however, you may also register class or closure based event listeners manually in the boot method of your EventServiceProvider:

    use App\Events\PodcastProcessed;
    use App\Listeners\SendPodcastNotification;
    use Illuminate\Support\Facades\Event;
     * Register any other events for your application.
     * @return void
    public function boot()
            [SendPodcastNotification::class, 'handle']
        Event::listen(function (PodcastProcessed $event) {
