Подскажите как сделать отображение пунктов меню по разрешению

    firebaseAuth = FirebaseAuth.getInstance();
        drawerLayout = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);

        navigationView.setNavigationItemSelectedListener(this);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawerLayout.addDrawerListener(toggle);
        toggle.syncState();
        if (savedInstanceState == null){
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new StatisticFragment()).commit();
            navigationView.setCheckedItem(R.id.statistic);
        }

    int itemId = item.getItemId();
        FirebaseFirestore database = FirebaseFirestore.getInstance();
        database.collection("users").document(FirebaseAuth.getInstance().getCurrentUser().getUid())
                .get()
