How to add ulx groups to the pointshop to let the people buy them

[deaddevil2299]

Hi Community 
I want to add ulx Groups like a "regular player" group to the pointshop with more rights to the let the people buy them when they have enough money.
Does somebody have an idea to add them to the pointshop.
Does somebody have an idea?

Console command for adding users is:
ulx adduser <playername> <groupname>

To retrieve the player's name through the pointshop function, you would use ply:Nick().
