MVVM and long query, how is it done?

Question

Android

There is a fragment and in it I receive data through retrofit, which are calculated from 1s to 30s, and at this time the orientation can change and start all over again. How is it done correctly when the result is expected for a long time?
I thought via IntentSrvice or so https://proandroiddev.com/rxjava-2-android-how-to-...
