Have you tried the _NET_SUPPORTING_WM_CHECK window’s _NET_WM_NAME?

https://specifications.freedesktop.org/wm-spec/1.5/ar01s03.html#idm46094431920896:

~~~
_NET_SUPPORTING_WM_CHECK

_NET_SUPPORTING_WM_CHECK, WINDOW/32

The Window Manager MUST set this property on the root window to be the ID of a 
child window created by himself, to indicate that a compliant window manager is 
active. The child window MUST also have the _NET_SUPPORTING_WM_CHECK property 
set to the ID of the child window. The child window MUST also have the 
_NET_WM_NAME property set to the name of the Window Manager.
