Azure AD b2b“读取所有用户的基本配置文件”权限

我已授予用户权限User.ReadBasic.All。在文档中，它指出了这一点

“允许该应用程序代表登录用户读取组织中其他用户的基本配置文件属性集。这包括显示名称，名字和姓氏，电子邮件地址，打开的扩展名和照片。还允许该应用程序阅读已登录用户的完整个人资料。”

如何获得所有具有基本个人资料的用户？

var accessToken = authContext
    .AcquireTokenAsync(graphResourceId, new ClientCredential(clientId, secret))
    .Result
    .AccessToken;

var graphserviceClient = new GraphServiceClient(
    new DelegateAuthenticationProvider(requestMessage => {
        requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
        return Task.FromResult(0);
    }));

您能否确认我的“ Authority” URL是否正确？

string authority = "https://login.microsoftonline.com/{tenantId}/common/oauth2/v2.0/token?&response_type=code&scope=openid%20profile%20User.Read%20User.ReadWrite%20User.ReadBasic.All";
AuthenticationContext authContext = new AuthenticationContext(authority);
var accessToken = authContext
    .AcquireTokenAsync(graphResourceId, new ClientCredential(clientId, secret))
    .Result
    .AccessToken;
