Hello Pascal

Google may have changed the terminology again, but I suppose you're referring to this part of our documentation:

• The first step in the OAuth consent screen is to select the User Type. Since your employees will be registering with their own Gmail accounts, you need to select “External”, and click on “Create”.

So, in your case it should say Public.

We'll go through the setup again, and make sure our documentation is altered if they changed this again.
