Connecting with a physical button

I'm using the CMF 2 pro by NOTHING and I want to make it so that my essential side button connects/disconnects me from the VPN. I already unbinded the button using canta and tried to use key mapper by sds100.

It has functions like send intent and input shell commands but as far as I know the android version of netbird doesn't have a shell command unlike the desktop's "netbird down/up".

So i was wondering whether someone has done anything similar and if yes, how did you do it?
