get a list of users that belong to a specific user group.

I had a similar request in the past, but was trying to identify which CTAs were created by Group XYZ, and realized that the Pool ID in the CTA object does not correlate either to the User Group GSID (but the relationship between them can be pulled from the backend). I see you are a Gainsight Employee, if you can access the ticket for the whole response, the ticket is #348334. It just dawned on me that I was meaning to submit an idea about this issue, but somehow I completely forgot.

And then import that data into DD via S3.

Fyi, I submitted the Idea:
