You can access what groups a member belongs to by navigating to the related tab of the member’s contact record and scrolling to the “Group Memberships” section.

This section can be confusing so it is advised to open the list view and filter down to active memberships only. To do this select the title “Group Memberships”, then using the funnel icon in the top right hand side of the page, add a filter for “Active = Checked” and apply.
