[POINTSHOP] How to set donators in Pointshop for TTT?

How do I set a pointshop exclusive group (Example Donator ) in TTT so only they get exclusive skins?

See here for information:

Don’t make two threads. Just ask how in your first one in which I already told you how to do this.

The first one was for specific players, not player groups. Sorry :I

You then asked how to add them to Donor groups as well.

ITEM.AllowedUserGroups = { "vip" }

Makes the Item Donator Only

CATEGORY.AllowedUserGroups = { "admin", "vip" }

Makes the Category Donator only
