title: How to integrate Firebase into Google Apps Script without using (deprecated) database secret
body: <p>For a while ago I was using <a href="https://sites.google.com/site/scriptsexamples/new-connectors-to-google-services/firebase" rel="noreferrer"><strong>integration of Firebase in Google Apps Script</strong></a> as a server side and it was working finely and still working in my old projects.</p>
  
  <p>But today after creating a new Firebase project and a new realtime database then trying to integrate Firebase Project into my <a href="https://script.google.com/" rel="noreferrer">Google Script project</a> I got <a href="http://prntscr.com/lfv727" rel="noreferrer">an error</a> and it's not working completely. And I realize that <a href="https://prnt.sc/lfv2n7" rel="noreferrer"><strong>Firebase deprecated database secret</strong></a> for new projects.</p>
  
  <p>So, my question now is how to come over this problem? Is there another way to integrate Firebase into Google Script project? </p>
