How is notifyd supposed to be started?

[Kai-Martin Knaak]

I noted that notifyd was not running on my Desktop. The application
itself is installed. It just wasn't running. I am able to start it
manually:

--------------------8<--------------------------------------
$ systemctl --user start xfce4-notifyd.service
$ systemctl --user status xfce4-notifyd.service 
● xfce4-notifyd.service - XFCE notifications service
     Loaded: loaded (/usr/lib/systemd/user/xfce4-notifyd.service; static; vendo>
     Active: active (running) since Sat 2020-03-28 17:58:49 CET; 9min ago
   Main PID: 7668 (xfce4-notifyd)
     CGroup: /user.slice/user-1000.slice/user at 1000.service/xfce4-notifyd.service

Mar 28 17:58:49 swips systemd[1577]: Started XFCE notifications service.
$
------------------->8----------------------------------------

Afterwards, the demon seems to work as expected. I can trigger a test
notification and applications successfully use the facility. 

So how and where is the notify demon supposed to be started in the first
place?
