My app is a chrome extension. (chrome browser). I'm trying to trigger a `SAVE` on the draft in gmail

gmail.js

 // compose is the compose window element
 // Here I'm clicking the x button on the compose window. But it Doesn't seem to work or trigger a save.
  $(compose).find('[aria-label="Save & Close"]').trigger('click');

 // select subject to trigger a Save, not sure if that works.
  $(compose).find('input[name=subjectbox]').trigger('select');

  // Reload Page
  $.ajax({
      url: window.location.href,
      headers: {
          "Pragma": "no-cache",
          "Expires": -1,
          "Cache-Control": "no-cache"
      }
  }).done(function () {
      window.location.reload(true);
  });

  // close Compose window
  $(compose).hide();

}
