Lua code help: Pointshop add item icons

Hey i was wondering if anyone could help me in figuring out how to add icons to specific items within original pointshop. Either by creating a new group with an icon, or individually for each item.

I’ve found this code which could be relevant.


function PANEL:PaintOver()
141		if self.Data.AdminOnly then
142			surface.SetMaterial(adminicon)


					ITEM.AdminOnly = false
100						ITEM.AllowedUserGroups = {} -- this will fail the #ITEM.AllowedUserGroups test and continue


	if ITEM.AdminOnly and not self:IsAdmin() then
202			self:PS_Notify('This item is Admin only!')

example item code:

ITEM.Name = 'AK47'
ITEM.Price = 2000
ITEM.Model = 'models/weapons/w_rif_ak47.mdl'
ITEM.WeaponClass = 'weapon_ttt_ak'
ITEM.SingleUse = false
ITEM.AllowedUserGroups = { "superadmin", "Super Donator", "Donator+", "Guardian", }

something like ITEM.SetMaterial = ruby work?

Thank you for any help and understanding <3

function PANEL:PaintOver()
   if self.Data.AdminOnly then
                local adminicon = "user_gray.png"
		surface.SetDrawColor( 255, 255, 255, 255 )
		surface.DrawTexturedRect(10, 10, 16, 16) 
    end --  if self.Data.AdminOnly then
end -- Paint
