SUMMARY Currently played song is not exposed to the Windows KDE Connect application in order to do the usual playback control with my Android KDE Connect application. I believe this issue is tied to Elisa because, for instance, playing videos on my web browser will properly allow me to control the playback. I currently am running the Elisa version named elisa-22.08.0-1247-windows-msvc2019_64-cl.exe downloaded from binary factory.
There's a specific Windows API we'll need to use — https://learn.microsoft.com/en-us/windows/uwp/audio-video-camera/integrate-with-systemmediatransportcontrols
