Problem with pressing a button(mobile)

[Dssall2]

local frame = script.Parent

local function onTouchTap()
	print(":D")
end


frame.TouchTap:Connect(onTouchTap)

So here I have a basic script that should output the inscription, but why do you when you click on the button output blank, what’s the problem?

you tested it on a phone/tablet right? because that would work
