How do I register a service?

[4drawing95]

I want to completely separate Maya by version as services. My job blocks sometimes need Maya and sometimes need Arnold. These two computers have each program installed separately, so I need clear distinction when sending jobs. That's why I tried to create services. Especially for Maya, since there are multiple versions, I distinguished them as "maya2023" and "maya2024", and I clearly specified the version accurately using the setService function in the Python code for the corresponding blocks. But surprisingly, it doesn't work. It's not that the job doesn't work after being submitted, but when I use the setService command, I get a log saying "Error: Unknown service 'maya2023', setting to 'generic'" and when the job is sent, it's sent as generic. So I tested with "maya" and it works perfectly. I think there must be additional work needed beyond simply creating the service in the GUI. Do you know how to do this?
