title: Manually Close native screen picker of getDisplayMedia
body: <p>Could I possibly close the native screen picker of getDisplayMedia({video:true}) without selecting an application to share?
  As far as I know, it automatically closes on track.stop() if a track being shared is stopped. However, there is an instance that I need to close the native screen picker without pressing cancel or selecting an application to share.</p>
