How can i change this script into OnClicked script?

I need help with making this script being OnClicked script, I have tried switching some stuff in the script and it didnt work.

print("Badge Awarder Loaded. BadgeID: " .. script.Parent.BadgeID.Value)




function OnTouch(part)
	if (part.Parent:FindFirstChild("Humanoid") ~= nil) then
		local p = game.Players:GetPlayerFromCharacter(part.Parent)
		if (p ~= nil) then
			print("Awarding BadgeID: " ..script.Parent.BadgeID.Value .. " to UserID: " .. p.userId)
			local b = game:GetService("BadgeService")
			b:AwardBadge(p.userId, script.Parent.BadgeID.Value)
		end
	end
end

script.Parent.Touched:connect(OnTouch)

If you're doing a part that triggers the function if it is pressed down, then it will be like this:

function OnTouch(part)
    -- Codes
end

script.Parent.ClickDetector.MouseClick:connect(OnTouch)

If it was a Gui, then the gui has to be TextButton, or other Gui that is clickable:

function OnTouch(part)
    -- Codes
end

script.Parent.MouseButton1Down:connect(OnTouch)
