I think all the three desktop platform support both running an application on background and launch it at system startup.
By “running on background” I mean running with no window and eventually display an indicator in the sys tray.
The second option, “launch at system startup”, is usually shipped with the first one.
Basically I’m asking for what most chat applications have.
