You can use base fragment, but it's just workaround. Actually, navigation component is still buggy. Here is an issue on GitHub. Example:

class SearchFragment : BaseBottomTabFragment() {

    private var _binding: FragmentSearchBinding? = null
    private val binding get() = _binding!!

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        _binding = FragmentSearchBinding.inflate(inflater, container, false)
        return binding.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        binding.buttonDynamicTitleNavigate.setOnClickListener {
            navigateWithAction(
                SearchFragmentDirections.actionSearchFragmentToDynamicTitleFragment(
                    binding.editTextTitle.text.toString()
                )
            )
        }
    }

    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    }
}
