Hello I want to make a GUI that only appears when a Player buy one of my Developer Products. Is this possible and how can i do it then ?

Thats my script to purchase it

local ClickDetector = Instance.new("ClickDetector", script.Parent)
ClickDetector.Name = "\0" -- a clickdetector with no name
ClickDetector.MaxActivationDistance = 32 -- set the maxactivationdistance to 32 studs
ClickDetector.MouseClick:Connect(function(plr) -- establish a RBXScriptConnection.
    game:GetService("MarketplaceService"):PromptProductPurchase(plr, 1069575853) -- change devProductId to ur devproductid.
end)
