Hello. I don't know if that's what you wanted to hear but technically,
the script is a big wrapper around
`call-process-shell-command'. `app-launcher--action-function' can be set
to whatever function to execute on the selected candidate, by default
this is set to `app-launcher--action-function-default' which ultimately
runs `call-process-shell-command'. See:
https://github.com/SebastienWae/app-launcher/blob/main/app-launcher.el#L167

Is this enough information?
