i'am sending push message by requesting https://fcm.googleapis.com/fcm/send with payload:

       $message = array(
            "notification" => array(
                "title" => $title,
                "body" => $body,
                "click_action" => $clickAction,
                "image" => $image,
                "icon" => $icon,
                "data" => array(
                    "link" => $clickAction
                ),
                "actions" => array(
                    array(
                        "action" => 0,
                        "title" => "Test"
                    )
                ),
            ),
            "to" => $to
            
        );

       $message = json_encode($message);

       ... curl to https://fcm.googleapis.com/fcm/send 

and it all works, but only "actions" do not work. When i got push notification, it has title, icon, image, body, but has no action button "Test"

Can anyone help? :)
