Query Latest Version Code of Uploaded Builds in Unity Editor

+1 this is important for being able to implement a decent deployment pipeline that can handle rollback with Oculus Platform Utility cli.
Can sort-of workaround this by intentionally failing setting an unused channel with a very old build in it and parsing the error.
e.g. to get the current release bundle version:

$ ./ovr-platform-util.exe set-release-channel-build --app_id <app_id> --app_secret <app_secret> source-channel ALPHA --destination-channel RELEASE > out.txt

Then regex parse the version code from out.txt
"ERROR: You are trying to add an APK with version code 12 to a release channel, but the previous APK on this channel has version code 80. The version code must be higher than the previous version code."

Do you still use this workaround?  Hard to believe there's no API for this.  It seems like the ovr-platform-util now doesn't care if you set a build to an older version - so it won't return the latest build number.
