Collection View Item clicked when selected

Question

For now, I have this:

    func collectionView(_ collectionView: NSCollectionView, didSelectItemsAt indexPaths: Set<IndexPath>) {
        print(indexPaths)
        }
    }

and it works when the item was not already selected. I'm looking for some way to catch when an item already selected was clicked. For example:

    func collectionView(_ collectionView: NSCollectionView, didClickItemsAt indexPaths: Set<IndexPath>) {
        ...
    }

EDIT: didDeselectItems doesn't fire by clicking on selected items
