how to start "minimized" startup applications in Gnome

Hi all,
I can easily add startup applications in gnome-tweak-tool, but how can I set them to start minimized please?
I’m trying to start chrome minimized (which I don’t use!) for having google hangouts starting at boot all the time (which I really use!), please see this post:
Many thanks

sorry, anyone? thanks :slight_smile:
