Watch does not receive the messages from phone

Hi

I've started trying integrating KDE Connect with watch. I'm using Garmin Venu as watch and Android 11 Motorola phone.

gitlab.com/.../BackgroundService.java

here I'm trying to send messages between Android phone and Garmin watch.

I was able to send messages from Garmin watch to phone (message is accessible and readable in 228 line of code. When I'm trying to send message from phone to device - it does not appear in logs. Also onMessageStatus is never called.

MonkeyC app code:

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

(Line 32 - registeration, callback on triggerLine 46 not triggered)

I'm understand I'm quite new to Monkey C development. I'm looking for some code or another open source Garmin app with working 2 sides Communications with Connect IQ.

Best Regards
