C# custom windows 10 lock screen text

  c++, uwp, windows, winforms, wpf

I have some trouble with the Windows 10 Lock Screen. I want to show their my "own text" programmatically with C# (like Spotify)

I tried something with UWP, I managed to get normal toast messages, but I couldn’t display any kind of text or badge on the lock screen.

I want something like on this image:

Thanks for any kind of help
