How to set toolbar title from fragment using Navigation UI Component

I have an activity with a toolbar from a default layout in Android Studio and I can easily change the title in the toolbar through the following method:

    Bundle bundle = new Bundle();
    bundle.putString("toolbarTitle", "A new title");

    NavHostFragment
        .findNavController(this)
        .navigate(R.id.action_navigation_conversation_to_placeholder, bundle);

Where safe args is already implemented for toolbarTitle in the navigation menu layout.

However now I am trying to change the title from the fragment that is opened via the method above, for example;

I do know how to update it without using Navigation UI Components, but I want to use them if it is possible.

Other similar questions are only related to the example I already provided above for when a new fragment is being opened or by suggesting the use of the typical method that does not make use of the Navigation UI Components, none cover this specific scenario.

You can change the the title by accesing the supportActionBar from the activity:

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    (requireActivity() as AppCompatActivity).supportActionBar?.title = "Your Title"
}

It seems like this is not possible with the only way to achieve this by doing it directly without using the Navigation Architecture Components.
