MVVM. How to transfer of complex data / commands from Domain to View

Briefly, the question is: in MVVM (AAC), how can Domain (business logic) manage the display of complex states / data in the View layer?

Now in more detail.

It means that inside the Domain: 1) received, calculated some data that need to be shown; 2) the state has changed, it is necessary to react to this (hide / show a group of widgets, call a new fragment, show / update progress, etc.). And it's harder to do than just show a message or a dialog, or just send LiveData to the RecyclerView.

Therefore, examples like "hello world" or "2 + 2 = 4" do not fit, everything is clear in them. In MVP, this is simply done. But here I was able to find the weak point of MVVM.

Now I did the following.

By means of RxJava2 (as an option, it can be LiveData from AAC) from Domain to View (via ViewModel AAC) an object that contains the type of command (enum) is passed and has a bunch of fields for data for all occasions (different fields for different commands of course ). And further, View contains a large switch-case, depending on the type of command where all this is handled.

Variant 2. To create a bunch of specific objects, and then in the View will sit a large if-instanceof.

Variant 3. Store data for View in ViewModel AAC (for which it is actually intended), and send from the Domain only the type of command, then View takes all the necessary data from the ViewModel.

Variant 4. A heap (in case of complex UseCases) a specific Observables in Domain and a heap of subscribers in the View.

So: is there (if any) a more elegant way? There may be some architecture pattern. Maybe I'm in vain reflexing, and this is the right way(s).

ps. 1) the "Command" pattern here does not exactly fit, 2) the "State" pattern has already been implemented by me, and it does not solve the problem either.
