@JonL and @jamesbond, I’m not arbitrarily looking at sub apps or wanting to manage users outside of my main app. Gmail has put in place very restrictive User Data policies and I’m looking for some type of solution. Although I may not be able to serve personal gmail users I may be able to serve G Suite Business users if they are housed within their own app.
Google’s policies require that only the Owner and users within a G Suite domain have data access.

Just an FYI if you are thinking of connecting to gmail in your app .
