Xamarin Form CollectionView Change Highlight Color

Question

I don't see an option to change Xamarin CollectionView Highlight Color (when pressing down and hold before release iOS). I want to change the default gray highlight color in iOS (Please don't confuse this with the selected collection view color, which we can change with VisualStateManager)

For those who stumbled upon this as well:

   public class ExtendedCollectionViewRenderer
   : GroupableItemsViewRenderer<GroupableItemsView, CustomGroupableItemsViewController>
{
     protected override CustomGroupableItemsViewController CreateController(
        GroupableItemsView itemsView,
        ItemsViewLayout layout)
    {
        return new CustomGroupableItemsViewController(itemsView, layout);
    }
}

public class CustomGroupableItemsViewController : GroupableItemsViewController<GroupableItemsView>
{
    public CustomGroupableItemsViewController(GroupableItemsView groupableItemsView, ItemsViewLayout layout)
        : base(groupableItemsView, layout)
    {
    }
    protected override UICollectionViewDelegateFlowLayout CreateDelegator()
    {
        return new CustomGroupableItemsViewDelegator(ItemsViewLayout, this);
    }
}

public class CustomGroupableItemsViewDelegator
    : GroupableItemsViewDelegator<GroupableItemsView, CustomGroupableItemsViewController>
{
    public CustomGroupableItemsViewDelegator(
        ItemsViewLayout itemsViewLayout, 
        CustomGroupableItemsViewController itemsViewController)
        : base(itemsViewLayout, itemsViewController)
    {
    }
    public override void ItemHighlighted(UICollectionView collectionView, NSIndexPath indexPath)
    {
        var cell = collectionView.CellForItem(indexPath);
        if (cell != null)
        {
            cell.SelectedBackgroundView = null;
        }
    }
}
