android - How to navigate from preference screen to a fragment?

Question

I am building an app where there is a settings screen which I build with Andreoid Jetpack Preference library. I want to travel from the preference screen into a more detailed fragment in order to personalize email. But I don know how to handle the click on the preference, I have managed to import the method provided from the library but I dont know how to implement it as there is no information available. I have the function onPreferenceClick but i dont know how to build its logic. It shall return false when it is not clicked and true when it is.

    override fun onActivityCreated(savedInstanceState: Bundle?) {
    super.onActivityCreated(savedInstanceState)

    if (onPreferenceClick(preferenceScreen.getPreference(1))) {
        findNavController().navigate(R.id.editMailFragment)
    }

    override fun onPreferenceClick(preference: Preference?): Boolean {
    preference?.setOnPreferenceClickListener {

        }
    }
    return
}

If you using PreferenceFragmentCompat, you can override onCreatePreferences to handle click on preference:

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {

        addPreferencesFromResource(R.xml.your_preference);

        Preference preferenceMap = findPreference("your_preference_key");

        preferenceMap.setOnPreferenceClickListener(
                new Preference.OnPreferenceClickListener() {
                    @Override
                    public boolean onPreferenceClick(Preference arg0) {
                        findNavController().navigate(R.id.editMailFragment)
                        return true;
                    }
                });

    }
