Hi :) Currently, I am developing Apple login. First of all, thanks to the official document you provided, we are proceeding with the development easily. We are in the process of verifying the identity token of the logged-in user. We would like to proceed with the process of saving (member registration) in our DB using the email that can be obtained from the token that has been verified. After signing up as a member, I want to create my own refresh token and maintain my login, so should I do the Generate and validate token, revoke token course? Is there any disadvantage? If the user disconnects Apple, we will delete the data from our DB.
