Smart contracts can never execute by themselves. Some entity always has to call them and pay for the gas fees.
That entity can either be a user of your marketplace or some backend service of yours. The easiest approach is that you simply add a function like terminateAuction which anyone can call, and which takes the auction ID (or however you identify them) as parameter, terminates that auction and settles the result (the sale). So probably the same as what you already have.
You can also configure your backend to call the termination. Then you simply need a bit more infrastructure: some way to call it right after an auction ends, way to manage the backend's wallet (since it needs Ether to pay for gas fees), connectivity and where&how to run this system.

Sorry, I don't have code available for this. But the function has basically just the following steps: 1) check that the auction has ended 2) check if there is a winner 3) perform the sale 4) close/terminate the auction Commented Jun 28, 2022 at 8:03
