Не работает транзакция между фрагментами android studio java

Есть два фрагмента. В одном установлен EditText, в другом Textview. Нужно передать имя с одного фрагмента на другой. Много чего перепробовал. От сохранения переменных разного уровня сохранности, до транзакций между фрагментами. Ничего не работает. Помогите, пожалуйста.

Код первого фрагмента:

'''

public class FirstFragment extends Fragment {

    private FragmentFirstBinding binding;


    @Override
    public View onCreateView(
            LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState
    ) {

        binding = FragmentFirstBinding.inflate(inflater, container, false);
        return binding.getRoot();

    }

    public void onViewCreated(@NonNull View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        binding.buttonFirst.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                 NavHostFragment.findNavController(FirstFragment.this)
                        .navigate(R.id.action_FirstFragment_to_SecondFragment);
            }
        });
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        binding = null;
    }
}

Остальное (MainActivity, nav_host_fragment, activity_main, content_main и прочее скину при необходимости). Надеюсь на оперативную помощь. Заранее спасибо
