Refreshing the token when access token is expired

I was able to add apple login in my iOS App. Unfortunately, the token expires every 24 hours.

I tried to follow the documentation: https://developer.apple.com/documentation/sign_in_with_apple/generate_and_validate_tokens but I get "invalid_client" error everytime..

Is there a real use case available somewhere to know which field is which?

Thanks
