No, domains, subdomains, and return URLs are considered separate values and should be explicitly registered to be whitelisted for use with Sign in with Apple.
If you’re enrolled as an individual, you can register up to 10 website URLs. If you’re enrolled as an organization, you can register up to 100 website URLs. You do not need to upload a file on your server to complete the registration process for domains and subdomains.
