Ionic push 'onNotification' when user disables notifications

With ionic’s new push notification service, if a user disables notifications for my app, how far up the chain does it block the notification?

When the app is open, can I hook into the notification using ‘onNotification’ even if notifications are disabled? Then maybe I can handle it locally instead of the content appearing as a global notification. I would like to use this instead of my own websocket / polling solution for real time data.

Anyone know if this will work?
