The idea is that the buyer and seller side worklets are able to register a URL with the browser in their reportWin and reportResult APIs. The registered URL is required to be attested for Protected Audience API. Please see [the Privacy Sandbox enrollment attestation model](https://github.com/privacysandbox/attestation#the-privacy-sandbox-enrollment-attestation-model).
