Hi @Anonymous
Okay, that's a new direction.
Do you want to list all the group members of one specific group?
If so, you need to use Office365Groups.ListGroupMembers function.
Firstly, you need to connect with office365 groups connector.
Secondly, set your drop down's Items:
Office365Groups.ListGroupMembers("group object id").value
Do not forget the ".value" part, or else you will get error.
What's more, you could find a group's object id in azure admin center:
