Using beforeFilter Event with custom eventListener class

MyController.php

<?php
namespace App\Controller;

use App\Controller\AppController;
use App\Controller\MyEventListener;

class MyController extends AppController {

	public function initialize() {
		// this sets up the eventManager, loads Components and the like.
		parent::initialize();
		$this->eventManager()->on(new MyEventListener($this->Auth));
	}
	
	public function index() {
	}
}

MyEventListener.php

<?php
namespace App\Controller;

use Cake\Event\EventListenerInterface;
use Cake\Controller\Component\AuthComponent;

class MyEventListener implements EventListenerInterface {
	private $auth = null;

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

	public function implementedEvents() {
		return [
		// THIS SHOULD RATHER READ:
		//	'Controller.beforeFilter' => 'beforeFilter',
			'Controller.initialize' => 'beforeFilter',
		];
	}

	public function beforeFilter(\Cake\Event\Event $event) {
		// you can use $this-auth now
		debug([$this->auth, $event]);
		throw new Exception();
	}
}

I see.
The document not mention this one and i don't know Controller.beforeFilter event does not exists.
Thank you.
