title: FCM push notifications on mutliple TWA on same domain
body: <p>I am working on a use case where I am trying to create multiple TWAs which run on same domain but with different routes. Like this</p>
  <ul>
  <li><p>TWA-1: <a href="http://www.example.com/pwa1" rel="nofollow noreferrer">www.example.com/pwa1</a></p>
  </li>
  <li><p>TWA-2: <a href="http://www.example.com/pwa2" rel="nofollow noreferrer">www.example.com/pwa2</a></p>
  </li>
  <li><p>TWA-3: <a href="http://www.example.com/pwa3" rel="nofollow noreferrer">www.example.com/pwa3</a></p>
  </li>
  </ul>
  <p>I have gone through this <a href="https://github.com/GoogleChromeLabs/svgomg-twa/issues/70" rel="nofollow noreferrer">thread</a>  to know that creating multiple TWAs on same domain is doable.
  But I am not able to understand how push notifications will work in this case.</p>
  <p>Since firebase credentials are same on the three TWA , so I assume that same FCM token will be generated for all three TWA(since they run on browser) . Now If I send a push notifications to TWA-1 , how do I manage to open the targeted TWA on notification click and not the other.</p>
  <p>Please excuse brevity.</p>
