Show and hide a View with a slide up/down animation android studio - kotlin

Question

I have a problem hiding the BottomNavigationView since there is a space left over and I don't know what to do in that case, I don't know what property to use so that the entire BottomNavigationView is hidden, I would appreciate any advice or solution to my problem

bottomNavigationView = binding.space as BottomNavigationView
val layoutParams = bottomNavigationView!!.layoutParams as CoordinatorLayout.LayoutParams

setContentView(binding.root)
initRecyclerView()
}
I don't know what to try
