Jetpack compose navigation architecture without fragment?

I am a bit confused about the new Jetpack compose navigation component androidx.navigation:navigation-compose documented at https://developer.android.com/jetpack/compose/navigation.

Am I right to say that the single-activity architecture with 0 fragment is preferred to the single-activity architecture with multiple fragments when using Jetpack Compose ?

I know we can still use fragments and Jetpack compose in this manner :

class MyFragment: Fragment() {
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        return ComposeView(requireContext()).apply{
            setContent {
                MyFragmentComposable()
            }
        }
    }
}

But I want to make sure that when using androidx.navigation:navigation-compose, we are not supposed to use fragment anymore, starting like so:

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