VLC on iOS does not fetch/play files from Google Drive

After logging into Google Drive, the app is not able to fetch the files from Drive. VLC player gives error "Error while fetching files - Insufficient Permission: Request had insufficient authentication scopes.". I logged-in to Google and I can see VLC for iOS to have access to "Basic account info" in the Google' security configuration page (Apps with access to your account). I think this access alone is not sufficient for fetching the files from Google Drive. I also have FlacBox app installed and it is able to play the files from Google Drive fine. I checked the permission it has got. It additionally has access to: Google Drive - See, edit, create, and delete all of your Google Drive files. I think VLC also needs to ask for this authentication scope.
