                ],
            ];
        }

For Add Editor Option, In Cross Sell etc or Custom Product Link option

Need to set editorConfig property of column so it display Text Box,

'editorConfig' => ['editorType' => 'text']

@Navin How were you able to save this value? I've been trying to create a new catalog_product_link_attribute, but have been out of luck. Any idea?
