Whats is the UIS difference between Touch and Click?

Hey. I have the test code below. It’s working totally fine when i touched down and swipe my finger on screen. It’s printing location. But with the mouse it’s not working. What am i missing in here? Of course i can do this with different methods but i would like to learn the logic.

UserInputService.InputBegan:Connect(function(input, gameProcessedEvent)
    if input.UserInputType == Enum.UserInputType.Touch or input.UserInputType == Enum.UserInputType.MouseButton1 then       
        input:GetPropertyChangedSignal("Position"):Connect(function()
            print(input.Position)
        end)
    end
end)
