I have a requirement for my app as follows:
There is an Office365 group containing a list of people with approval authority from across the organization.
I need to create an approvers list field in my app that only displays people from that group whose department matches that of the current user.
Is there any way this can be achieved? The Office365Group.ListGroupMembers function does not appear to return the department, so can't just run a simple filter on the results.
