How to add padding to my UI to avoid being obscured by display cut-out when in landscape orientation?

Question

I still want the bottom navigation bar to remain the same length, but I want to add some padding in the container to the left to shift the cards over to the right a bit. I have the following code in my MainActivity.kt right now:

WindowCompat.setDecorFitsSystemWindows(window, false)
    ViewCompat.setOnApplyWindowInsetsListener(binding.root) { view, windowInsets ->
        val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
        view.updateLayoutParams<ViewGroup.MarginLayoutParams> {
            topMargin = insets.top
        }
        binding.bottomNavigationView.updatePadding(bottom = insets.bottom)
        WindowInsetsCompat.CONSUMED
    }

My activity_main.xml is composed of a ConstraintLayout that encloses two elements: BottomNavigationView and FragmentContainerView.

Fixed it thanks to @Zain's help!

private var cutoutDepth = 0

override fun onCreate(savedInstanceState: Bundle?) {
    [...]
    ViewCompat.setOnApplyWindowInsetsListener(binding.root) { view, windowInsets ->
        val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
        cutoutDepth = insets.top
        [...]
    }
    [...]
}

override fun onResume() {
    super.onResume()
    // Starts the orientation listener
    if (orientationListener.canDetectOrientation())
        orientationListener.enable()
}

override fun onPause() {
    super.onPause()
    // Stops the orientation listener
    orientationListener.disable()
}

private val orientationListener by lazy {
    object : OrientationEventListener(applicationContext, SensorManager.SENSOR_DELAY_NORMAL) {
        override fun onOrientationChanged(orientation: Int) {
            if (orientation == ORIENTATION_UNKNOWN)
                return
            when (display?.rotation) {
                Surface.ROTATION_0 -> {
                    // Bottom - reset the padding in portrait
                    binding.navHostFragmentActivityMain.setPadding(0, 0, 0, 0)
                }
                Surface.ROTATION_90 -> {
                    // Left
                    binding.navHostFragmentActivityMain.setPadding(cutoutDepth, 0, 0, 0)
                }
                Surface.ROTATION_180 -> {
                    // Top - reset the padding if upside down
                    binding.navHostFragmentActivityMain.setPadding(0, 0, 0, 0)
                }
                Surface.ROTATION_270 -> {
                    // Right
                    binding.navHostFragmentActivityMain.setPadding(0, 0, cutoutDepth, 0)
                }
            }
        }
    }
}

End result:
