Now my main activity look like

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        val viewModel = ViewModelProvider(this).get(MainViewModel::class.java)

        val navHostFragment = supportFragmentManager.findFragmentById(binding.fragmentContainerView.id)
                as NavHostFragment

        binding.bnvBase.setupWithNavController(navHostFragment.navController)

         binding.toolbar.ivBack.setOnClickListener {
             supportFragmentManager.commit {
                 replace(R.id.fragmentContainerView, PokemonCardsFragment())
                 setReorderingAllowed(true)
                 addToBackStack(null)
             }
         }

         binding.toolbar.searchButton.setOnClickListener {
             supportFragmentManager.commit {
                 replace(R.id.fragmentContainerView, SearchPokemonCardsFragment(
                     binding.toolbar.searchSrcText.text.toString()
                 ))
                 setReorderingAllowed(true)
                 addToBackStack(null)
             }
         }
    }
