Can't connect acl to cakephp3, what's wrong?

Question

PHP

In cakephp3 acl is connected as a plugin, but unfortunately this event is not documented. I decided to try using guides for cakephp2, installed the plugin, connected it as a component, generated an aco tree through the console.
I have the division of rights only by groups, according to the guide, I need to add to the model:

public function bindNode($user)
    {
        return [
            'model' => 'Group',
            'foreign_key' => $user['User']['group_id']
        ];
    }

there as in keyyke3 model (both in table and in entity).
Further it is not possible to set permissions, it gives a series of errors
