How can I find the path of objects in another Max Audio Effect in M4L?

I'm trying to just monitor gain of each part of an effect rack. I use the "Pathfinder" to find the path for stock Ableton Live plugins, but it doesn't seem to work on custom Audio Effects. Let me know if there's anything I can clear up!
It may be because you are targeting non-Live objects ? Replacing Max standard [gain~] by [live.gain~] may work ?
Ahh thank you! I was using [live.meter~] but it's not interactable so it wasn't working. [live.gain~] does get recognized but when I reference it in another script it's just the I guess MIDI parameter of gain modifying the volume, and not actually the gain being passed through that track.
Any ideas how to get this value?
