How can I add a map of all a BuddyPress group's members?

I got the GoogleMaps plugin because I wanted to be able to add a map to each group on my BuddyPress site of all the members of that group.

I’m not sure how to do that exactly with the Plugin, it says I can use it with Groups, after adding the add on, but I don’t understand how to configure it for that.

Thanks in advance,
