Brightness slider works but fn keys don't

Hi! I have a Lenovo V15 G2 ITL running the latest Manjaro version, with all packages up to date. I’m having issues getting the brightness FN keys to work. The rest of the keys do work (Playback control, volume control, Mic mute, screenshot, even the calculator one), and the brightness slider also works.

Here’s the system information:
