CakePHP 4 and Auth Plugin - Remember Me doesn't work

Hi there,
I installed the authentication plugin on a fresh CakePHP 4 project. Enabled regarding the documentation and it works for session-based auth. I want to add remember me functionality, so added
->add(new EncryptedCookieMiddleware(['CookieAuth'], Configure::read('Security.cookieKey'))) to the $middlewareQueue variable in Application@middleware. There is no any explanation how to generate the cookieKey actually, but I used a random string to test. Also added

     $service->loadAuthenticator('Authentication.Cookie', [
            'fields' => $fields,
            'loginUrl' => '/users/login',

remember me field is remember_me by default. So I added <?= $this->Form->control('remember_me', ['type' => 'checkbox']); to the login form. I tried to check it and login, but it doesn’t add the cookie to the browser when I check with Chrome DevTools.

What am I missing?

Thanks in advance.
