title: How to use Firebase Database in Google Actions?
body: <p>I'm new to programming Actions for Google Home/Assistant.
  I have been using the Inline-Editor under Fulfilment lately and it works fine. Now I want to start using the Firebase DB. 
  As it says <code>const functions = require('firebase-functions');</code> in the first lines of the Inline Editor I am assuming, that the Database is ready to use?
  If so, how do I access it?</p>
