How can I get System.println logs from my physical device?

Hello,

I have a Venu 3 and develop my own apps for that.

I often have issues thaqt aren't really happening in the simulator, but only on the real device.

How can I get the logs from my Venu 3?
I have the ciq-log.txt but that only outputs crashes, not the debug logging I have with System.println.

I heard you need to create a txt file in GARMIN/apps/logs/appname.txt but I don't really know what the app name is when the app was installed from the CIQ store (I do that to debug issues on my devices of my family members or fro mysyelf as Settings don't work if I sideload it).

The app ID from the manifest can be ruled out as that doesn't work...

Thanks in advance+
