How do i get a button working on ipad and phones?

So I have these buttons in my Roblox game which are donations and they work perfectly fine on my laptop but when I play the game on my iPad and phone. They don’t work. How do I get the buttons to work on mobile devices ?. Do I need to add a script for touch screen??? I would really love the help. Basically the button does show up just doesnt do anything when i touch it on the screen yet when i click it when im on my laptop it does what its suppose to do. (let you by the pass.)

this is my script i have but for the button. is they anything i need to change about it ??

local plr = game.Players.LocalPlayer local button = script.Parent local MarketplaceService = game:GetService("MarketplaceService")

script.Parent.MouseButton1Click:Connect(function() MarketplaceService:PromptGamePassPurchase(plr, 9963718) end)

local plr = game.Players.LocalPlayer 
local button = script.Parent 
local MarketplaceService = game:GetService("MarketplaceService")

button.MouseButton1Click:Connect(function() 	 
       MarketplaceService:PromptGamePassPurchase(plr, 9963718) 
end)
button.TouchTap:Connect(function()
       MarketplaceService:PromptGamePassPurchase(plr, 9963718)
end)

You can also use Activated for it to work with both:
