Claiming back funds in credit on PayPal credit account

Description

Just wondering if anyone knows how to claim back money they have in credit on their PayPal credit account? Basically I bought some goods online and paid my PayPal credit balance in full pretty much soon after but then due to unforeseen issues I ended up having to send the goods back for a full refund. I’ve now been left with money in my PayPal credit account and not sure how to claim it back as I’m not going to be using my PayPal credit account again in the near future???
