@jordie you can add Retool as a configured app. Go to your configured apps, choose Add App, and OAuth App Name Or Client ID. Search for Retool and select their listings. When you authenticate again you'll see Retool is no longer blocked, and it will ask for permissions to access your GA services.
I tried to log in to my admin account but it seems like, there is no such account. I don´t understand... I haven a google analytics and google cloud account connected but don´t seem to have an admin account. Can anyone help?
Once again, I clarified we are not using Google Workspaces and so we don´t have an admin account for pur domain. Is there a way I can access the "self hosted" version of the API as seen in your documantation?
