TrackID in Ableton via API

Hey, i wanna have the TrackID from Ableton Live where my M4L patch is.

I couldn't find a solution in the Track Abstractions: https://docs.cycling74.com/max5/vignettes/core/live_apiabstractions.html

I know i can get the ID when the patcher is highlighted in Ableton Live (M4L.api.GetSelectedTrackIndex.maxpat), but i wanna call the id from another patcher via send/return from another Ableton Track. My problem is when i "call for" the ID from my "caller" patch, i just get the ID where the "caller" is inside, not the actual TrackID from the patch in another Track.

I wanna jump from a remote-control patcher to all my patches inside Ableton Live, and therefore i need the Track ID from all my M4L patches.

Hope someone understands the question..

Thanks Markus
