Try window.get_property("window").export_handle()?  Your previous
example (and error message) shows that window.get_property("window")
gives you a GdkWaylandWindow, and usually Python method names match C
function names without the type prefix.

(I cannot find any mention of GdkWayland on https://lazka.github.io/pgi-docs,
which is usually my go-to site for Python GTK binding questions.)
