Displaying item after clicking back bottom navigation view

Question

When I press the back button, it opens the previous fragment. But in the bottom navigation, another tab remains highlighted.

How do I make the tab on the bottom navigation change when the fragment changes too?

private lateinit var mainBottomBar: BottomNavigationView

private val navigationBottomViewListener = NavigationBarView.OnItemSelectedListener {
    val fragment = when (it.itemId) {
        R.id.homeMenu -> HomeFragment()
        R.id.pomodoroMenu -> PomodoroFragment()
        R.id.statisticsMenu -> StatisticsFragment()
        else -> return@OnItemSelectedListener false
    }

    replaceFragmentWithAddBackStack(fragment)
    return@OnItemSelectedListener true
}

private fun replaceFragmentWithAddBackStack(fragment: Fragment) {
    supportFragmentManager.beginTransaction().addToBackStack(null).replace(R.id.mainContainer, fragment).commit()
}

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    mainBottomBar = findViewById(R.id.mainBottomBar)
    mainBottomBar.setOnItemSelectedListener(navigationBottomViewListener)
}
