findNavController() not working for bottomNavigationBar

Question

I have a bottom navigation bar as an activity, in which i have three fragments, i.e. HomeFragment, GameFragment, WalletFragment.

The bottom navigation bar is working fine and i am able to move between the three fragments.

From the HomeFragment on the press of a specific button, i want to navigate to a different fragment which is not a part of navigation bar. For this purpose, i am using findNavController().navigate(action)

But as soon i am tapping on the button, my app crashes and i am thrown to the very first framgment of my app.

Below is the full code that i am using to navigate:

binding.getStarted.setOnClickListener {
  val action = HomeFragmentDirections.actionLandingFragment ()
  findNavController().navigate(action) 
}

The Runtime Error i am getting is:

androidx.constraintlayout.widget.constraintlayout does not have a navController set

Ps: I've tried to do this with explicit intent, but the app is still crashing on the press of that button
