External power button (in addition to current button)

Hello,
Does anyone have any experience attaching an external power button to the Argon One v2 case? I have mine in an arcade cabinet and I would like to utilize the safe shutdown feature of the case, but don’t want to have to reach inside the cabinet to do so. I’m hoping there is a way to piggyback the same pins that the built-in switch is using, or to modify the script somehow to also look for the signal on a different set of pins (if piggybacking isn’t possible).
