How do I make the ui clone once everytime each part gets clicked?

I have an issue with my code, I can't seem to only clone once when a player clicks on the item/part once in the workspace

	local objects = require(game.ReplicatedStorage.Modules.Objects)
	function CreateUI(name, parent, quantity)
		local Template = game.ReplicatedStorage.Guis.Template:Clone()
		Template.Parent = parent
		Template.quantity.Text = quantity
		Template.Name = name
	end
	clicks = {}
	game.ReplicatedStorage.Events.Pickup.OnClientEvent:Connect(function()
		for _, items in pairs(game.Workspace:GetChildren()) do
			if items:IsA('Part') then
				if items.ClickDetector.MouseClick then
					CreateUI(items.Name, game.Players.LocalPlayer.PlayerGui.GameUi.InventoryUI.InventoryInset, "5")
					if game.Players.LocalPlayer.PlayerGui.GameUi.InventoryUI.InventoryInset:WaitForChild(items.Name) then
						
					end
				end
			
			end
			
		end
	
	end)

Ignore objects.
