Help with Firebase cloud saving

So everything works fine, i followed some tutorials, but nowadays no new tutorials added..

So my question would be how to get data from this table? would be perfect if you show me C2 code

My saving C2

And what i see in Firebase (everything is correct)

I'm using Firebase api v3, Auth and Itemtable plugins for this.

So how do i get data from firebase? As you can see in code i using "Authentication.UserIDFromProvider"

UP, now i know how to get (load) but, when now when im exporting to cordova what plugins should i use?
