registerForPhoneAppMessages NOT WORKS in Garmin Venu

I tried to write KDE Connect client for Garmin, but I can't make registerForPhoneAppMessages to work

Code of the app is here:

MonkeyC

https://gitlab.com/thecyberd3m0n/kdeconnect-android-garmin/-/blob/main/monkeyc/KDEConnectIQ/source/KDEConnectIQApp.mc

Android service:

https://gitlab.com/thecyberd3m0n/kdeconnect-android-garmin/-/blob/main/android/src/org/kde/kdeconnect/BackgroundService.java

Result:

After trying different data, debugging and multiple failures I found another Open Source app

https://github.com/andan67/wormnav

I've compiled both apps, added some logs and problem persists - onPhone never gets logged into watch, callback is never called (onPhone on watch and onMessageStatus on companion app). I can see only registerForPhoneAppMessages. Also no exceptions, nothing.

I've forked wormnav with logs to demonstrate the problem:

I've reported it in Bug Reports - forums.garmin.com/.../registerforphoneappmessages-not-works-in-garmin-venu, I can't find the way to remove it from here

it seems like a watch is very selecting about the incoming message format.

Format data as ArrayList<String>. As far I tested ConcurrentList, List<Object>, or naked String not works

Despite trying some of the things you have mentioned I am still not able to communicate between watch and phone. Sometimes the phone correctly tells the watch to open the CIQ App but then I am not able to send or receive any messages using Comm.transmit(). I am not sure why the bug report was set to complete because even with the Comm Android Sample and Comm CIQ App sample I am not able to send or receive messages.
