Android Binding after AndroidX migration

I'm having some issues with a library that I upgraded:

I'm getting the following issue:

1>BINDINGSGENERATOR : warning BG8604: top ancestor OneMoreFabMenu not found for nested type Com.Dekoservidoni.Omfm.OneMoreFabMenu._1.

In that specific section, I have the following code:

override fun onStartNestedScroll(coordinatorLayout: androidx.coordinatorlayout.widget.CoordinatorLayout, child: OneMoreFabMenu,
                                     directTargetChild: View, target: View, nestedScrollAxes: Int, type: Int): Boolean {

        return nestedScrollAxes == ViewCompat.SCROLL_AXIS_VERTICAL || super.onStartNestedScroll(coordinatorLayout, child, directTargetChild, target,
                nestedScrollAxes, type)
    }

And I have added these NuGets:

Any idea, which one could I miss?
