Whenever to send systembus-notify notifications.
WARNING: enabling this option (while convenient) should *not* be done on a
machine where you do not trust the other users as it allows any other
local user to DoS your session by spamming notifications.
To actually see the notifications in your GUI session, you need to have
`systembus-notify` running as your user, which this
option handles by enabling {option}`services.systembus-notify`.
