GNOME Shell does not *really* use the binary name to match .desktop
files, but the WM_CLASS (X11) or application-id (wayland) property.
GTK+ sets those from the program name, either determined automatically
or from the value specified by g_set_prgname() - that is, you should
be able to fix this issue by calling that function with an appropriate
value before creating the first window.
