title: Problem in publishing chrome extension to chrome webstore with key field in manifest.json
body: <p>We are trying to publish our chrome extension on webstore but it's giving an error while uploading zip the error is that can't upload chrome extension with key field in manifest.json .
  The key field we added to manifest.json was for Oauth2, we used for authentication of users with google.
  Now when we published our extension without key field it's being uploaded without any error but Oauth is not working.
  Any of you has any idea about this problem please help us.</p>
