Yii2 how to specify which controller to apply action in AccessControl?

Question

Yii

Here is the code that is written in the AppController from which all the rest are inherited:

public function behaviors()
{
    return [
        'access' => [
            'class' => AccessControl::className(),
            'rules' => [
                [
                    'allow' => true,
                    'actions' => ['index'],
                    'roles' => ['?'],
                ],
                [
                    'allow' => true,
                    'roles' => ['@'],
                ],
            ],
        ],
    ];
}

For an unauthorized user, only action => index is allowed, but there is one such action for each controller, is it possible to indicate that an action belongs to a controller in a rule?

Answer 1

This should be written in the controller itself, not in the parent class.
Why do this in the parent, if this rule will still apply to 1 controller?
