Adding Sign in with Apple to an Existing project using Auth0

Hey Auth0,

I am attempting to add the SIWA feature in order to get approved for the AppStore. Up until now the process has been fairly repetitive (Twitter, Discord, Google), however, Apple is doing Apple and I am getting an error page when attempting to SIWA.

Things I’ve Tried:

Adding the Team and Key IDs Adding SIWA to my current Identifiers in Apple Developer portal Adding SIWA “Capabilities” in the XCode IDE for the project, thus Revoking and reinitializing the Provisioning Profile Verified dev tenant

Hunches:

There are many tutorials that mention adding a “Service Id” for SIWA on the Apple Developer portal, however because I have already registered the apps reverse url for other Identities Apple gives me an error that the Identifier has already been used.

Another is, many tutorial mention adding callback urls, which is typical for social connection providers using Auth0, however it isn't obvious based on Apples documentation or UI where to add the callback URLs.
