How can I detect if a player clicks/taps the screen without clicking/tapping any GUI?

In a local script inside of StarterPlayerScripts, I put:

local userinputservice = game:GetService("UserInputService")

userinputservice.InputBegan:Connect(function(input, gameProcessedEvent)
    local inputType = input.UserInputType
    if inputType == Enum.UserInputType.MouseButton1 then -- When a player clicks the screen
        if gameProcessedEvent == true then -- If the player pressed a button.

        else
            -- Put your code here
        end
    end
end)

This will run your code where it says "Put your code here" if the player presses a screen. It won't run when a button is pressed but will work if you press a TextLabel.
