Combine multiple filter in single alias filter

Source: https://codeigniter4.github.io/userguide...ml#aliases 

In CI4 documentation, is written, for use single alias, and multiple filter, set $aliases in this mode:

PHP Code:

public $aliases = [
        'csrf' => \CodeIgniter\Filters\CSRF::class,
        'toolbar' => \CodeIgniter\Filters\DebugToolbar::class,
        'honeypot' => \CodeIgniter\Filters\Honeypot::class,
        'authrequest' => [
            \App\Filters\ValidHeaders::class,
            \App\Filters\IsAuth::class,
        ]
    ]; 


and my routes is configure in this mode:

PHP Code:

$routes->group('api/v1', function ($routes) {

    $routes->resource('authentication');
    $routes->group('authentication', function ($routes) {
        $routes->delete('/', 'Authentication::revoke', ['filter' => 'authrequest']);
    });

}); 


But I received this error:
