Enable Live Chat for member of a special group only

We have added a new custom role within SmaterTrack.
Then we can assign the role to new or existing users.
Now they are member of that group. That's fine.
But you can not configure to display the Live Chat (on the portal) for user of this group only.

Example: Display Live-Chat for Customer with a premium support contract only.

Please add this to the wishlist.
