Woocommerce invoice number missing in Klarna merchant portal

I am using the KCO plugin and I noticed that the Woocommerce generated invoice number does not get into the Klarna Merchant Portal.
In the merchant portal, there are two fields that currently have the Woocommerce order number. I would like to have one of these fields populated with the Woocommerce invoice number once the order gets to the “Completed” stage (and the capture of the order via Klarna is triggered).

After having reported this to Klarna, I was told this is something that “This has to be implemented in your Woocommerce shopsystem.”

My support question: How can I accomplish this using the KCO or Order management plugins (or a code snippet that assigns the correct value into the correct field following the order getting a ‘completed’ stage) ?
