ProximityDevice NFC events not triggered / NFC doesn't work at all

[minze-it]

Just wanted to mention an issue from the WindowsAppSDK that somehow doesn't have any place right to be posted/reported.
microsoft/WindowsAppSDK#4356

Describe the bug

was first posted as issue here: 

https://github.com/microsoft/microsoft-ui-xaml/issues/9358
then here: https://learn.microsoft.com/en-us/answers/questions/1604064/windows-app-proximitydevice-nfc-events-not-trigger
reported via feedback hub...
contacted our Microsoft consultant
He sent us back to this... this is really frustrating - nobody really cares

We have an app that we migrated from UWP to WinUI 3 a while ago.
Unfortunately, we discovered that with the WinUI 3 app the ProximityDevice NFC feature no longer triggers events / no longer works at all. We use simple code that can be found in many examples and have set

var proximityDevice = Windows.Networking.Proximity.ProximityDevice.GetDefault();
var messageSubscriptionId = proximityDevice.SubscribeForMessage("NDEF", (device, message) =>
{
Console.WriteLine(message.Data.ToArray());
});

this works in UWP and doesn't work in WindowsAppSDK/WinUI3 App
See min Repo examples
Works: https://github.com/minze-it/BlankProximityUWP
Doesn't work: https://github.com/minze-it/BlankProximityMaui
Steps to reproduce the bug

What do I need to do to use NFC in a WindowsAppSDK app, or where should I report a bug for errors affecting Windows.Networking.Proximity?
