How to subscribe to LiveData in ViewHolder

I now can not understand how to do it.

I have a RecyclerView in ViewHolder I make bind fields and data to show the user.

So I give the LiveData to LiveData to subscribe to it in ViewHolder , but

 public void observe(@NonNull LifecycleOwner owner, @NonNull Observer<T> observer) 

accepts a LifecycleOwner owner which is not in the ViewHolder

there is a method

 public void observeForever(@NonNull Observer<T> observer) 

which needs nothing.

So the question is

1) how correct it is to subscribe to LiveData in ViewHolder

2) if so, is it necessary to transfer to the ViewHolder LifecycleOwner or to subscribe to observeForever and that's it?
