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

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

MainActivity.kt

class MainActivity : AppCompatActivity() {

    private lateinit var binding: ActivityMainBinding
    private var bottomNavigationView: BottomNavigationView? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)

        bottomNavigationView = binding.space as BottomNavigationView
        val layoutParams = bottomNavigationView!!.layoutParams as CoordinatorLayout.LayoutParams
        layoutParams.behavior = ScrollHandler()

        setContentView(binding.root)
        initRecyclerView()
    }

I don't know what to try
