g15daemon extra keys not working

I have a g15 logitech keyboard and would really like to get the extra keys (m1g1-m3g18) working.

I installed g15daemon. It seems to run fine, the clock shows up on the g15 display when I start it.

The LEDs of the extra keys don’t light up however and the keys are not usable.

In ‘Keyboard’ I have Logitech | Logitech G15 extra keys via G15daemon selected.

I imagine that Wayland does not know about the necessary key symbols, but I don’t know how to fix that.
