Brightness control on Sonoma 14.5 + OCLP 1.5.0 #14

Hi! has anyone been able to have brightness control on Sonoma 14.5 installed with OCLP?

So far I've been able to control screen's brightness on Catalina installing it using dosdude's patcher without installing the backlight patch.

Today I tried Ventura with OpenCore LegacyPatcher and I found no way to make the brightness control to work, nothing's shown on the screen when the keyboard's buttons are pressed.

So far I have installed the following macOSes and found the same behavior:

macOS Big Sur 11.5.2 + OCLP 1.5.0 macOS Big Sur 11.5.2 + OCLP 0.6.8 macOS Big Sur 11.5.2 + OCLP 0.6.8 as MacbookPro8,1 (shot in the dark) macOS Ventura 13.6 + OCLP 1.5.0

BTW, I booted Ubuntu 16.03 and the brightness works just fine with F1 and F2. So at Sierra, High Sierra, Catalina and Ubuntu 16.03 brightness works fine

I have just tried building OCLP 1.5.0 from source code in order to avoid the Legacy GMUX installation, installed macOS Sonoma 14.5 and brightness didn't work so it doesn't seem to be because of the Legacy GMUX root patch. I wonder if another macOS version and/or disabling other patches would make it work but doing this tests takes time.
