Can't find toggle for automatic brightness in plasma 6.6

Hello,

I wanted to try new feature with automatic brightness, but I can’t find it anywhere in settings.

I own a macbook 12 (9.1). Sensor seems to work fine. When I run a command `sudo cat /sys/bus/iio/devices/iio:device0/in_illuminance_raw` I get a number of some sort. That number changes when I bring my palm in close proximity to sensor.

Oh, nearly forgot to mention, I use arch linux as my OS.

Best wishes,

Gene
