All public apps that access Google APIs must verify that they accurately
represent their identity and intent as specified by Google’s API Services
User Data Policy.
Depending on the scopes your app uses, you might need to undergo a more
thorough OAuth verification process. Learn more about
OAuth API verification.
If you change any of the details that appear on your OAuth consent
screen after your app is approved, you need to have your
app re-verified in order for the updates to be published to your OAuth
consent screen.
If you want your app to be available publicly, submit it for app review.
Otherwise, if you want your app to be available to only your organization,
it doesn’t need to be reviewed.
Once your app passes OAuth verification and app review, the app listing becomes
live in the Google Workspace Marketplace, or for Chat apps, in Google Chat.
