title: Google analytics on my React app with firebase SDK
body: <p>I used Google Analytics a lot for many sites...</p>
  
  <p>I'm just releasing a first app with Firebase (Firestore + Firebase SDK with reactjs).</p>
  
  <p>Then, I activated GA from my Firebase dashboard... but I cannot see any activity !</p>

  <p>I probably need not to add plugin like "autotrack" ? </p>
  
  <pre><code>import 'autotrack';
  ga('create', 'UA-XXXXX-Y', 'auto');
  </code></pre>
  
  <p>It's not clear because, it's impossible to find out the track ID (UA-XXXXX-Y) from my dashboard !</p>
  
  <p><strong>Do I really need it ? Where can I find it ?</strong>
