Push notification auto generated locally after X time

I’ve got an App using push notification, How can I implement when the notification generated is ignored, it can be auto generated locally after X time to inform the user accept or reject any event. Any idea guys?

If the push is ignored, you can’t do anything locally as you app is not even running.

What you can do is send a request to your backend when the push notification is opened. If this does not happen, you send another push, and another, and another… from the backend.
