Google Analytics error - app is blocked

[FCSEM_PPC]

I've successfully connected to other Google resources (Sheets, BigQuery, etc.). But I tried connected to Google Analytics via Oauth 2.0 and got this error: This App is blocked, etc.

I haven't had this issue before - does anyone have any suggestions?

If you head to the google admin console -> security -> apps. You can give retool access explicitly. This doesn't seem to be documented anywhere though
