How to manage BottomNavigationView backstack in Android Navigation Component

I am using navigation component and BottomNavigationView, i am facing a problem, that is when i go to from fragment 1>2>5>4>3 and when i press back button i get fragment 1. I know this is the default behavior but i don't want this, i want to save them in backstack so when i press back button it should go to fragment 4 not 1. I have been trying and searching but i couldn't find any solution. Can i put fragment manually into backstack in kotlin?

My code:

activity_main.xml

<androidx.constraintlayout.widget.ConstraintLayout
           .......................
           .......................>

            <androidx.appcompat.widget.Toolbar
               ................
               ................/>

            <fragment
                android:id="@+id/app_nav_host_fragment"
                android:name="androidx.navigation.fragment.NavHostFragment"
                android:layout_width="0dp"
                android:layout_height="0dp"
                app:defaultNavHost="true"
                app:navGraph="@navigation/app_nav"
                ..............
                ............../>
            <com.google.android.material.bottomnavigation.BottomNavigationView
                android:id="@+id/app_bottom_nav_view"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:background="@drawable/white_grey_border_bottom"
                app:menu="@menu/bottom_nav_menu"
                app:labelVisibilityMode="unlabeled"
                ...........
                .........../>

</androidx.constraintlayout.widget.ConstraintLayout>

app_nav.xml

<navigation 
    ...........
    ...........
    android:id="@+id/app_nav"
    app:startDestination="@id/homeFragment">

    <fragment
        android:id="@+id/homeFragment"
        android:name="com.example.instagram_clone.ui.HomeFragment"
        android:label="HomeFragment"
        tools:layout="@layout/fragment_home"/>
    .............
    .............
    .............
    .............
</navigation>

MainActivity.kt

class MainActivity : AppCompatActivity()
{
    override fun onCreate(savedInstanceState: Bundle?)
    {
        super.onCreate(savedInstanceState)

        val binding  = DataBindingUtil.setContentView<ActivityMainBinding>(this, R.layout.activity_main)
        val bottomNavView = binding.appBottomNavView
        val navController = findNavController(R.id.app_nav_host_fragment)

        bottomNavView.setupWithNavController(navController)

    }
}

As per the documentation on onNavDestinationSelected() (the method that setupWithNavController() uses when selecting a MenuItem):

By default, the back stack will be popped back to the navigation graph's start destination. Menu items that have android:menuCategory="secondary" will not pop the back stack.

So just add android:menuCategory="secondary" to each of the menu items used with your BottomNavigationView.
