An X application just sets properties on its top-level window and that's it.
Some messages received by the app come from the window manager, but the app
often doesn't know or care whether they came from the wm. X apps are designed
to work even if there's no wm. To send and receive detailed messages between
the app and wm requires a private protocol known to both. See wmctrl

NET protocol in wm-spec.html specifies nothing more than a bunch of
X properties that are set on the root window and application top-level
window just like the old non-NET properties. It specifies nothing about
telling the WM to do anything. They're all just hints.
