Having access to Push object from Ionic.io Push Service

Good morning everyone,
I’m using Ionic.io push service for my application but I’m having some trouble because I need to use the .clearAllNotifications() method and I can’t find a way to do it. It seems there’s no way to interact with the original plugin object but only with the minimal set of method exposed by Ionic.io service.

There is a way to get access to it and use it’s own method?

Thank you!
