How to assign a collaboration group to a resource/user in Fusion field service.

Summary: I am working to set up collaboration in Fusion Field Service. I set collaboration permissions for our user types on the user type General tabs. I also created collaboration groups. I see that the field, Collaboration Group[collab_assigned_user_group], is not available to be added to the edit resource/user page so I can't assign users to a collaboration group in Fusion field service. My assumption is that since the field is a user entity field it will now be managed in Fusion, but I cannot find the documentation on how to setup collaboration in Fusion Field Service. Can someone provide the steps I need to take or direct me to the documentation?
