If I am correct, this section is not available in standard ISO20022 CT file. The mentioned XML tags comes under RelatedRemittanceInformation. You have to make a customization on this. When payment order is created together with a payment advice, RmtLctnMtd can be set as True with value EMAIL. The email address can be fetched from AP supplier contact. Theoretically, this element should be handled as an optional XML block. But, if you do a customer specific modification, you might be able to hardcode the value EMAIL and fetch the AP supplier contact email to the XML. If you need further clarification, please feel free to DM.
