Values for Custom Field?

We are using WP All Import to import 1000s of products and want to automatically create a custom tab for some product data. What value do we need to import data into the custom field for the custom product tabs? We have found the “yikes_woo_products_tabs” custom field but we have to put in a key and a value.

So what is the key and the value for the yikes_woo_products_tabs custom field?

Thanks and best regards!
