How do I make a Reveal hint button in my Find The Button game?

I'm trying to make a game that is like Find The Button where you go around a map and press a button to go onto the next stage but I'm trying to make it when you buy a Developer product then it reveals where the button is?

This should work:

local productId = --Insert Product ID Here
local BuyProductBtn = --Insert The Location Of The Button You Click To Buy This Product
local function RevealPass(player)
	game:GetService("MarketplaceService"):PromptProductPurchase(player,productId) 
end
BuyProductBtn.MouseButton1Click:Connect(function(RevealPass)

Hope this helps! Leave a comment if it doesn't and I will try to fix it.

local script:

local mps = game:GetService("MarketPlaceService")
script.Parent.MouseButton1Click:Connect(function()
mps:PromptPurchase(game.Players.LocalPlayer, Id)--set Id to your product id
end)

server script:

function process(info)
local playerId = info.PlayerId
local players = game:GetPlayers()
local player
for i = 1, #players do
if players[i].UserId == playerId then
player = players[i]
end
local Id = info.AssetId
if Id == "Id" then --set the Id between the quotes to your product id
local beam = Instance.new("Beam", workspace)
beam.Attachment0 = player.Character.HumanoidRootPart
beam.Attachment1 = workspace.Button -- set this to the button name
end
end
local mps = game:GetService("MarketPlaceService")
mps.ProcessReceipt = process

Tell me if this works! It should create a beam that points towards the button for ease of finding.
