Integration of a GCP platform without Google Workspace

Hello Community,

We have a usecase for managing some technical accounts in a GCP tenant
So we try to use the out of the box Google Workspace connector and follow the documentation : https://support.oneidentity.com/fr-fr/technical-documents/identity-manager/9.2.1/administration-guide-for-connecting-to-google-workspace 

But the catch is that we don't rely on any Google Workspace, all admin users are from Office365.

So any idea how to make it work?

BR,
