Logitech G Hub LUA script for slow down scroll speed

Question

I own a G604 mice and I need to change the rows scroll only for Excel and Calc. I found in another thread a script that allows scrolling with keys, not exactly what I'm looking for but the biggest problem is that it scrolls 3 lines at a time since Windows has this setting.

This is the script I'm testing:

function OnEvent(event, arg)
   if event == "MOUSE_BUTTON_PRESSED" and arg == 5 then
      repeat
         MoveMouseWheel(1)
         Sleep(50)
      until not IsMouseButtonPressed(5)
   end
end

How can I change the parameter MoveMouseWheel so that it scrolls only 1/3?
