title: File creation and download, Drive scopes, and publishing editor add-on
body: <p>I'm working on an Forms add-on which would allow you to export survey response data and/or save it to user's Drive. Is there no way to do this other than allowing full Drive access through the most extensive scope?</p>
  
  <p>And about publishing editor add-on, how does one go about with it? I'm unable to get it to G-Suite marketplace, and the original unlisted version was on Chrome Webstore. (which is now unavailable)</p>
  
  <p>I tried to test it with "Integrate With Google" via the G-Suite Marketplace API, but nothing shows up when testing. I don't know why, since the add-on works as expected via "Test as extension" from Google Apps Script editor. And the "waiting for review" has been taking ages. Is there any way to know the status of it?</p>
  
  <p><strong>EDIT:</strong> It seems like only Drive API can be used with custom scope (after enabling it), but DriveApp always requires full-access scope. And the functions that fetch files from Drive ONLY give out those that the script has access to (created or opened with) if you're using  <code>drive.file</code> scope.
  ...the publishing part is still a mess though.</p>
