I have an Angular Service which lets me load data using HttpClient.request(...) and returns the data as an Observable.
Within my ngrx SignalStore I call these service methods within rxMethod()s.

One of my service methods does not have any parameters. So calling it within an rxMethod() is not an option, because rxMethod() requires a parameter, be it

a static value, signal, or observable as an input argument

What is the best practice in this case? I’d rather not use a normal SignalStore method, because I’d like to not have to bother with subscription management.
