How to get X Window belonging to a GtkDrawingArea in gtk4?

I was trying to port GUI integration tutorial of gstreamer(https://gstreamer.freedesktop.org/documentation/tutorials/basic/toolkit-integration.html?gi-language=c) from gtk3 to gtk4. I am hitting an issue with getting the X window belonging to GtkDrawingArea. In gtk3, to get the XID and to pass it to GstVideoOverlay following approach is used:

static void realize_cb (GtkWidget *widget, CustomData *data) {
  GdkWindow *window = gtk_widget_get_window (widget);
  guintptr window_handle;

  if (!gdk_window_ensure_native (window))
    g_error ("Couldn't create native window needed for GstVideoOverlay!");

  /* Retrieve window handler from GDK */
  window_handle = GDK_WINDOW_XID (window);

  /* Pass it to playbin, which implements VideoOverlay and will forward it to the video sink */
  gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY (data->playbin), window_handle);
}

I'm not able to figure out how to do the same in Gtk4. Since Gtk4 is using Wayland terminology, the function in gdk to get XID is GDK_SURFACE_XID() which takes a GdkSurface* as an argument and there is no direct function in GtkWidget to get the pointer to the GdkSurface similar to gtk_widget_get_window in Gtk3.

I tried getting GtkNative using gtk_widget_get_native of the GtkDrawingArea and getting GdkSurface attached to it but that is returning the surface of the GtkWindow.

I am looking for a way to get XID to pass to gst_video_overlay_set_window_handle to be able to play video in the widget.

I am fairly new to both Gtk and Gstreamer so apologies for gaps in my understanding.
