I don’t think that Macbook is officially supported. Did it work previously with other Linux distributions?

Controlling the keyboard led lights on a Macbook Pro running linux is harder than it should be.
For ...reasons the bundled `kbdlight` doesn't work, so we're left with no option but to roll
up our sleaves and get our hands dirty. Fortunately various bash commands and `bc` makes this
task pretty trivial so here is a script to control the brightness.
This script supports the following api:
$ kbdlight -set 10
$ kbdlight -set +10show original
kbdlight
#!/bin/sh

# Keyboard Backlight control for linux.

set -o errexit # abort on nonzero exitstatus
set -o nounset # abort on unbound variable

I found the solution for my MacBook here:https://aur.archlinux.org/packages/macbook-lighter
Edit: paru macbook-lighter should work.
Yup, tried kubuntu and ubuntu, and the keyboard backlight automatically turned on
