You need to go to the Design Code Profile Card and click on the tab "Team Members". From there you will find Identities (which are group of users) or users with their "Role".

If you want to see the "Role" in the Team, you can search in PLM Desktop for a Part or CAD Document with its Design Code, open it with this Design Code and click on the button to open the Team with all Identities inside and its roles.
