authorize method

Future<String> authorize({ String? clientId, required String redirectUri, List<String>? scopes, String? agt, List<String>? channelPublicIds, List<String>? serviceTerms, List<Prompt>? prompts, String? loginHint, String? codeVerifier, String? nonce, String? kauthTxId, bool webPopupLogin = false, })

사용자가 앱에 로그인할 수 있도록 인가 코드를 요청하는 함수입니다. 인가 코드를 받을 수 있는 서버 개발이 필요합니다.
