User provisioning in Google Workspace

When using GitLab to provision users in Google Workspace, I have a master repository (as shown below) and a pipeline in place but need some general guidance as I did not set this up and trying to see how I can add a Google group for all users that are provisioned with the existing pipeline.

Existing pipeline is working and need to update with this new requirement of adding a Group for all new users.

I’ll appreciate the input.
