We include a private hidden .desktop file for evolution's calendar
component, so that we can explicitly open that component when
evolution is configured as the default calendar application.
That's because the evolution developers didn't want to ship
additional .desktop files at the time, but they have since
then included a desktop action that can be used for the same
purpose.

Sandboxed apps that run without a window are detected by the new
background monitoring service, introduced by xdg-desktop-portal.
We have an opportunity to improve the predictability of the desktop
and ensure that application state in transparently reported to users
by showing these apps, and allowing them to closed.
Add a new background apps menu to the quick settings, that is always
added at the bottom of the popover, and has a slightly custom, flat
style applied to it.
Show background-running apps in this menu, and allow closing them
by first attempting to execute the 'quit' action through D-Bus, and
if that fails, sending SIGKILL to the process.
