HttpError 403 "AccessNotConfigured" for GroupSettings #2283

After setting up groupsettings service, I attempted to do an update method... but got this error message:
[ERROR] HttpError: <HttpError 403 when requesting https://www.googleapis.com/groups/v1/groups/TECH.XYZ%40jerseystem.org?alt=json returned "Groups Settings API has not been used in project 28547294957 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/groupssettings.googleapis.com/overview?project=28547294957 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.">

I've searched through our Google API console looking for project=28547294957 .... and cannot find it... which leads me to ask... where did the python code actually determine (or did it determine) a project to work against... Even if I create a project in Google (in fact I do have a project with googlesettings API enabled), where/how would I identify this... When I try the link, I get:

Troubleshooting info:

Missing permissions:
resourcemanager.projects.get

Not sure what steps to take at this point.... anyone have a suggestion?
