Momentary Power-Button and LED

[sebr]

Hello,
I have trouble getting a momentary power Switch and power LED to work at the same time. If I set
system.power.switch=PIN356ONOFFRESET
then the LED works as expected but the momentary power button does not.
If I set
system.power.switch=PIN56PUSH
the power button works well but the LED is off.
So after doing some research I cam across this post: https://forum.recalbox.com/topic/5701/momentary-power-button-with-led
So I changed the lines mentioned in the script but not success: power button still not respond. How to adjust the script to make it work?
