I have a Chrome extension that uses a sensitive OAuth scope. My GCP OAuth app is still in testing mode / unverified.

Two quick questions: 

  1. Can CWS approve an extension before OAuth verification is completed on GCP? 
  2. Will CWS reviewers be blocked or see an "unverified app" warning when testing the OAuth flow during their review?

Trying to understand if both processes are truly independent. Thanks!

I don't believe we have a specific way of handling this so it could go either way. Your item may be approved, but I also wouldn't be surprised if it was flagged for having broken functionality. If you can get the OAuth client approved beforehand, that would be my suggestion.
