title: PWA with TWA: How to force Chrome instead of default browser
body: <p>I have built a PWA with TWA &amp; generated APK following the official Google guide here - <a href="https://developers.google.com/web/updates/2019/02/using-twa" rel="noreferrer">https://developers.google.com/web/updates/2019/02/using-twa</a></p>
  
  <p>What's happening is that when a different browser apart from Chrome is set as default, the behaviour is unpredictable. For example: on a Xiaomi phone where MI Browser is the default, my app works just as a shortcut &amp; the page just loads in one of the tabs of the browser. This phone had Chrome installed, but my app still used the default browser to render my PWA.</p>
  
  <p>Official documentation states the following:</p>
  
  <blockquote>
    <p>Today, if the user's version of Chrome doesn't support Trusted Web activities, Chrome will fall back to a simple toolbar using a Custom Tab. It is also possible for other browsers to implement the same protocol that Trusted Web activities use. <strong><em>While the host app has the final</em></strong> say on what browser gets opened, we recommend the same policy as for Custom Tabs: use the user's default browser, so long as that browser provides the required capabilities.</p>
  </blockquote>
  
  <p>While the guide has this paragraph, I'm unable to find any documentation on how to set a preferred browser for my PWA</p>
