AirPods 4 ANC not showing on checkoverage website despite adding to iCloud

On the checkoverage website, my AirPods 4 ANC are not displayed. When I try to search by serial number, a window pops up saying that I need to add them to iCloud. Although I believe I’ve done everything — all set up and connected — what should I do?

Add the device to iCloud.

The service coverage information cannot be displayed because there is no data available for this device — only the device owner can provide it. First, pair this device with your iCloud account.
