FileProvider NSFileProviderReplicatedExtension

Hello everyone.
In macOS 11.0 there is a new api related to fileprovider. Can anyone explain how to use this api , or maybe a simple sample code that is using this API.
Currently I am trying to create a fileprovier by implementing the protocols for macos 11.0. and add simple logs just to see it working. In Console I always see these logs:

com.apple.xpc.launchd[1] (com.corp.testprovider.testproviderextension[985]): Extension did not initialize in time.
com.apple.xpc.launchd[1] (com.corp.testprovider.testproviderextension[986]): Extension is hanging on launch. Killing.


Some additional information related how to use this api will be very helpful.
Thanks.
Still, having an example how to use the new NSFileProviderReplicatedExtension would really be helpful.

As long as Apple does not provide an official sample code, @Laszlo, @sssddgg could you maybe post your code here as a starting point for other developers? Thanks a lot!
I found this example, which looks promising: https://github.com/peterthomashorn/macosfileproviderexample/tree/main

Sample code is available here: https://developer.apple.com/documentation/fileprovider/macos_support/syncing_files_on_macos
