Need Help: HowTo start to programm a first app: "Pause" (break or "face down") for Xperia 10 III

I had to install “Situations” again, which I did from the Jollastore. Then I opened a terminal on the phone and started Situations again with the command “harbour-situations2application”
After that, I opened a ssh-connection from my pc and got the following status:

● harbour-situations2application.service - Situations Background Serv
ice
   Loaded: loaded (/usr/lib/systemd/user/harbour-situations2application.service;
 enabled; vendor preset: enabled)
   Active: active (running) since Mon 2022-10-10 21:13:21 CEST; 57s a
go
 Main PID: 9234 (harbour-situati)
   CGroup: /user.slice/user-100000.slice/user@100000.service/harbour-situations2
application.service
           └─9234 /usr/bin/harbour-situations2application server

Tomorrow I’ll test it again and post the status, when I observe the malfunction again.
