            Describe how the neighbor cell(s) must be connected to the current
            cell to be considered as a neighbor.
            Can be either ``'points'``, ``'edges'`` or ``'faces'``.

        n_levels : int, default: 1
            Number of levels to search for cell neighbors.
            When equal to 1, it is equivalent to :func:`pyvista.DataSet.cell_neighbors`.
