How to use MVVM for Recycleview loadmore action

Thank you for your article. I would like to know, according to Android Official Guide of Unidirectional Data Flow, should I call uiState.Success(newAllList) when I pull more data, or add a new state: uiState.SuccessLoadMore(appendList)?

In the first case, I need to use DiffUtil ,If I have a large list but only want to append 20 pieces of data to it, is it not worth the loss? I prefer to use the second method and then call adapter.notifyItemRangeInserted(). I am very confused about this. How do you recommend I do it? Thank you very much for your answer.
