Hi, I'm developing the "sign in with apple" button. When I get the response from apple I can check the 'state' variable but what's the best way to know that the response actually comes from apple and not something else?

Hi, I need to make a "Sign with apple" button. I followed all the instructions and I managed to get apple's response with id_token. I have to continue testing the application but I no longer get the "user" object (name, lastname). How can I get the user object back to continue development?
