The launched KWin instance connects to your Wayland server, binds to the Shell and will create a ShellSurface. That you will get through a signal on m_shell - compare wayland_server.cpp:148. I would as a next step try to hook into this and see whether the surface gets created. Once you have that you can look into rendering it.

There's a damaged signal which you should use to trigger a repaint of your QQuickItem. When rendering you can access the buffer on the SurfaceInterface. If KWin uses KWIN_COMPOSE=Q you can access the buffer as a QImage and just render it. Pretty straight forward - hopefully. But first try to see whether you get the ShellSurface created. If not we need to look into what goes wrong.
  
  
  I've added the slot for checking if surface gets created but signal doesn't get emitted. Would you please show me the way to proceed further now.
