alarm-clock-applet starts application (if selected) but doesn´t stop it when alarm is cleared

my system: Linux/Lubuntu 18.04 LTS, 64 bit.
alarm-clock-applet: 0.3.4-1build1 amd64

Hi,
Man -pages say:

Notification can be done by either playing a sound, launching an application, showing a notification bubble, or any combination of the aforementioned options.

So I want to use alarm-clock-applet with the option "launching an application".
As a command I entered:

firejail --private mplayer "http://swr-swr3-live.cast.addradio.de/swr/swr3/live/mp3/64/stream.mp3"

That works well. When the respective alarm-time is reached the live-stream of SWR3 radio-programme is played.
But when I click on "stop all alarms" SWR3 keeps on playing.

In contrast to that it´s easy to stop the alarm whenever I use the "Playing a sound"-option.

It would be nice if alarm-clock could also stop the command when the alarm is cleared.

Thanks a lot in advance.

Greetings.
