githubLogin property
GithubLogin is the account to link. Used only when IAM holds no linked account for the provider — a linked account is stronger proof and always wins.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? githubLogin;
