Rx is now completely removed from Element dependencies. Some examples of the changes:

         sharedActionViewModel
                .observe()
                .subscribe { handleQuickActions(it) }
                .disposeOnDestroyView()

became

        sharedActionViewModel 
               .stream()
               .onEach { handleQuickActions(it) }
               .launchIn(viewLifecycleOwner.lifecycleScope)

Inside fragment use

launchIn(viewLifecycleOwner.lifecycleScope)

Inside activity use

launchIn(lifecycleScope)

Inside viewModel use

launchIn(viewModelScope)

Also be aware that when using these scopes the coroutine is launched on Dispatchers.Main by default.
