Have pressing the power button briefly immediately shutdown the laptop?

I am on Ubuntu 24.04 LTS, and I want even briefly pressing the power button to immediately shut down my laptop (preferrably even when the laptop is locked and the screen is off) I have tried setting it in Settings Power, modifying logind.conf with HandlePowerKey=poweroff and PowerKeyIgnoreInhibited=yes, deleted logind.conf, now it's gone though, not coming back it seems. And using acpi cat /etc/acpi/events/powerbtn event=button[ /]power action=/sbin/poweroff none of these seem to enable the power button to do anything when (briefly) pressed. No LSB modules are available. Distributor ID: Ubuntu
