[TRACKING] "auto-brightness" aka ambient light sensor in Linux? Details?

Hi. The ambient light sensor works by default on Fedora, but on Arch does not. Has anyone had a success with making the auto brightness regulation work in Arch? What type/model of ambient light sensor is used in Framework laptop by the way? I found nothing on ArchWiki about that, tried Autolight from AUR which also doesn’t work. Please advise.
Update. Fonund the solution that worked for me by running the bash script from that guy:

Upd2: The script launches but works kind of weird, seems not regulating the brightness in dependence with the ambient light.
