Refund from escrow?

I started a trade today (BUSD/USD) with another user. When I got to the “fund escrow” step, I made a mistake. I sent funds to the correct address, but I didn’t enter the “memo”. So the buyer never saw the BUSD coins.

We then agreed to cancel the trade, and we started another trade, which went smoothly.

Now, I need to get a refund of the BUSD coins that went into escrow. How do I do that?
