I believe it is not the one you are looking for. The right one is here. Just scroll to MiHome screen shots and use the link right before the version number (currently 5.4.5). Screen shots shown are from earlier MiHome versions so do not pay much attention to them.
You will need to remove the official version and install this one. If after that you go to ‘General settings/Network info’ menu item for any device you will see the token there.
