Naming Convention for Methods Returning RxJava Completed

Question

I have an Android app with a view class ( Fragment, Activity) watching it ViewModel.

ViewModelprovides methods such as getUserNamewhich returns Observable<String>. Although it may be possible to find a better name (maybe observeUserName), I am pleased with the current one - this is quite explanatory.

However, the tricky part begins here: ViewModelit can also show that the view is performing some operation - for example, closing itself, pop-backstack, etc. In this case, ViewModeldefines the following method (and the corresponding one Subject):

class ViewModel {
   // other methods, fields

   // ViewModel can call returnToPreviousScreen.onComplete()
   CompletableSubject returnToPreviousScreen = CompletableSubject.create();

   Completable returnToPreviousScreen() { return returnToPreviousScreen; }
}

In my opinion, the name of the method is terrible. Hover, I can't find anything better. Something like this observeWhenToReturnToPreviousScreenmay be more explanatory, but difficult to read.
