How to use this with NavController

[Zunnorain]

I am trying to add this to NavControllers in order to replace fragments.
Another way is to use fragment transactions to replace fragments like this tutorial:

But that's not what i wanted. Kindly provide some way to use NavController

Eg:

val navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host_fragment) as NavHostFragment
navController = navHostFragment.navController
setupWithNavController(binding.bottomNav, navController)<==== Error here

Currently gives error at setupWithNavController(binding.bottomNav, navController)
