I am working on app that uses Navigation pattern. Now I have an Activity and few fragments. Each Fragment has a unique functionality so I created a separate toolbar for each fragment: collapsing, usual or no toolbar at all. I used the following example: https://android.jlelse.eu/instagram-style-navigation-using-navigation-component-854037cf1389

It works pretty well, but now I am taking an issue if I want to set some menu items in the toolbar.

For example, I would like to add a settings menu to the toolbar of the Profile Fragment

I tried setting a menu item, but it simply never appears and I think the method doesn't get called at all..

Is it possible to solve this issue without changing the whole architecture logic?

override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        binding = DataBindingUtil.inflate(inflater, R.layout.my_layout, container, false)

        setHasOptionsMenu(true)

        return binding.root
    }
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        binding.toolbar.apply {
            setupWithNavController(findNavController())
        }
    }
  override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
        inflater.inflate(R.menu.main_menu, menu)

        super.onCreateOptionsMenu(menu, inflater)
    }

    override fun onOptionsItemSelected(item: MenuItem): Boolean {
        if(item.itemId == R.id.action_get_info)
            Toast.makeText(context!!, "test message", Toast.LENGTH_SHORT).show()

        return super.onOptionsItemSelected(item)
    }
<?xml version="1.0" encoding="utf-8"?>
