adjust laptop brightness in win11 via hotkey?

Does anyone know how, preferably using Ahk?

On most laptop keyboards, you’ll find shortcut keys that allow you to quickly increase and decrease your brightness.

If the shortcut keys aren't working, usually it's because you have to install the software from the laptop manufacturer that allows these special 'Fn keys' to work. For example, on a HP laptop you need to make sure that "HP hotkey support" software package is properly installed. On my Medion laptop it is called Pegatron Hotkey (PHotkey). With my Logitech K800 keyboard I can just press Fn+F5 and Fn+F6 to adjust the brightness, while using no additional software of any kind.
