You can't, unless your users use an extension to move the legacy
systray from the bottom to the top, or to display an additional
indicator when your application is running - the top right corner is
considered a system area that applications should not mess with, so
there is no officially supported API you could use (the network icon
is not provided by an external process, but implemented in gnome-shell
itself).
