title: ios PWA(add to home screen) is not asking for Camera permission in Angular for video tag
body: <p>I have created PWA using angular in which I am using <code>zxing-ngx-scanner</code> library, which library for barcode scan. In ios browsers(Safari, Chrome and Firefox) and on Android it's asking for camera permissions and it's working fine, but if I add my site to homescreen(in ios), then it's not asking me for the camera permissions.</p>
  
  <ul>
  <li>I have hosted my site on HTTPS</li>
  <li>All PWA functionality working fine</li>
  <li>I am using  tag for the barcode scan</li>
  </ul>
  
  <p>Please let me know if anyone has any suggestions?</p>
  
  <p>Thanks in advance </p>
