Answer 1

You're looking for event.data.ref. From the reference documentation:

Returns a Reference to the Database location where the triggering write occurred. This Reference has the same end-user permissions as the client that did the write. So, if an unauthenticated client did the write, this Reference is unauthenticated. If the client that did the write is authenticated as a certain Firebase Auth user, this Reference is authenticated as that same user.
