How can I refund an order older than 6 months on PayPal?

Hi, I want to issue a refund on an order that was placed in December 2021 - when I try to process the refund I receive the message that the the timeframe to refund the order has expired.

The customer paid with Paypal if that’s relevant.

How can I process this refund via Shopify, so it’s accounted for in our payouts?

Thanks.
