title: Delete and Rename events in google drive
body: <p>I am working on a feature for our webapp where we create google drive files from our server</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>Drive service =  getServiceForLoginUser();
  
  com.google.api.services.drive.model.File fileMetadata = new com.google.api.services.drive.model.File();
  fileMetadata.setTitle(getDefaultName());

          com.google.api.services.drive.model.File.Thumbnail thumbnail = buildThumbnail(driveType);
  fileMetadata.setThumbnail(thumbnail);
          
  com.google.api.services.drive.model.File googleFile = service.files().insert(fileMetadata)

  <p>I have configured Drive UI Integration  to trigger New and Open URL flows from google drive.I have also published a chrome app with following manifest.</p>

  <p>So now I can trigger New and Open flows  in drive successfully. In New flow I create first a resource in our db and then I create a file in google drive from my application server. So every entry I create in google drive has a representation in our db as well. My issue is now if I rename or delete the file in google drive how do I get those events so that I can make the necessary changes in our DB ?</p>
