What menu are you talking about here?

If this is about popup menus, e.g. right click menu, "hamburger" menu,
etc, these are all surfaces drawn by the client (yourself), and mapped
using "xdg_popup" role (part of the xdg-shell protocol extension).

If this is about the "window menu" which is usually what shows up when
you right click on the title bar, this is (optionally) drawn by the
compositor, e.g. done by kwin or gnome-shell. This menu is shown by the
client issuing the "show_window_menu" request on the xdg_toplevel
object.
