Powershell attribute to distinguish where a group was provisioned?

Today there is not determistic way of knowing where the group is created from via PowerShell. This is something we have on our backlog and don't have a date we can share.

Using ExchangeProvisioningOption is NOT recommended since not all apps leverage it plus you can create a Teams against an existing Group for instance and this is not reflected in the script below.

Best you can do today is leverage the audit logs instead.
