If you want to stick to LiveData you can always use Transformations.map so that you don't have to observe in the ViewModel but rather only in the Fragment/Activity.

Otherwise, you can use SharedFlow, a single event observable. For more, I have written an article here: https://coroutinedispatcher.com/posts/decorate_stateful_mvvm/

You don't have to pass viewLifecycleOwner in the ViewModel because there is no point in calling observe in the ViewModel when the View just needs the latest result after all.
