title: Open Background Restriction in settings
body: <p>I need to show a warning to user if <strong>Background Restriction</strong> is applied (<code>Android 9 and higher</code>) and ask them to disable it.<br>
  What Intent I can use to open "Background Restriction" settings of my app and show it to user?</p>
  
  <p>Note : I am not looking for background data, but background activity.</p>
