title: Is there an alternative to the chrome feature flag "CommandLineOnNonRooted" to test a TWA
body: <p>I am trying to use a TWA as explained in the original documentation (<a href="https://developers.google.com/web/updates/2019/02/using-twa" rel="nofollow noreferrer">https://developers.google.com/web/updates/2019/02/using-twa</a>). I tried setting the chrome flag <code>Enable command line on non-rooted devices</code> to <code>Enable</code>, but Chrome is telling me after the relaunch that <code>You are using an unsupported feature flag: CommandLineOnNonRooted. Stability and security will suffer</code>. I tested this on two real Android phones, one on Android 10, one on 9. I also tested it with multiple emulator devices on different Android versions but I am getting the same error message.</p>
  
  <p>Is there any other way to test that the URL bar is not visible in the TWA, without the verification on the website part?</p>
