KDE Plasma. Changing the screen brightness with the NVIDIA driver

Hi, I have an NVIDIA discrete card + KDE Plasma. When I first started the system, the brightness slider was still there, and working. After installing a proprietary driver in a Wayland session, it is gone, although it works in an X11 session. Even when I installed the nvidia driver before installing plasma through additional packages in archinstall, the brightness slider appeared, but it just made the picture darker in the Wayland session, and the monitor brightness remained at 100% at the hardware level.
Is this something I can fix myself, or is it a bug?

I noticed that sudo ddcutil setvcp 10 100 changes the brightness, but there is still no control over this in the KDE interface
