remapping the power button on my laptop keyborad

Hi!
I have this Acer C720 Chromebook that runs Slackware64. I'm running a Wayland session.

It has the power key in the normal keyboard above backspace. From my other laptop I expect the delete key in this place. In this other thread I already managed to disable the key instantly shutting down the laptop.

This is how I did it:

1. in /etc/elogind/logind.conf I set HandlePowerKey=ignore
2. in /etc/acpi/events/default I commented out
   Code:#event=.*
   #action=/etc/acpi/acpi_handler.sh %e(only comments left in the file)

But now I'm not receiving events in xev for the power button. I think I did before, but I'm not sure.

The keyboard is /dev/input/event0 and the power button is /dev/input/event2. So how could I map the power button to delete?
