Export description from add. fields in the open map

https://partstore.crm-onebox.com/admin/auto/action/hour/edit/ The integration with opencards (export of products) is set up, by default the description is downloaded from the system field, but the same field is used by us in other integrations (prom, socket), we need the description for opencard with add. product fields. The action has the setting "Export settings for additional product fields". https://prnt.sc/vks1pa Tell me how to use this to export the product description from the add. product fields (to which column and table in the database to download)
