C# 使用openId connect如何向请求c添加声明#

我正在使用openId connect对用户进行身份验证

services.AddAuthentication(sharedOptions => { })
                .AddCookie().AddOpenIdConnect("QuickBooks", "QuickBooks", openIdConnectOptions =>
                {
                    openIdConnectOptions.Authority = "QuickBooks";
                    openIdConnectOptions.UseTokenLifetime = true;
                    openIdConnectOptions.ClientId = qbclientId;
                    openIdConnectOptions.ClientSecret = qbSecret;
                    openIdConnectOptions.ResponseType = OpenIdConnectResponseType.Code;
                    openIdConnectOptions.MetadataAddress = qbMetaAddress;
                    openIdConnectOptions.ProtocolValidator.RequireNonce = false;
                    openIdConnectOptions.SaveTokens = true;
                    openIdConnectOptions.CallbackPath = "/signin-oidc";
                    openIdConnectOptions.ClaimActions.MapUniqueJsonKey("realmId","realmId");
                    openIdConnectOptions.ClaimActions.MapUniqueJsonKey("id_token", "id_token");
                    openIdConnectOptions.GetClaimsFromUserInfoEndpoint = true;
                    openIdConnectOptions.Scope.Add("openid");
                    openIdConnectOptions.Scope.Add("phone");
                    openIdConnectOptions.Scope.Add("email");
                    openIdConnectOptions.Scope.Add("address");
}

我想用realmId检索用户数据

这在他们的请求中是可选的 主张

可选。包含应用程序正在请求的一组用户声明的JSON对象。这些声明要么在ID令牌中返回，要么在UserInfo响应中返回。现有索赔包括：

realmId—与用户关联的特定QuickBooks公司的领域ID

“id_令牌”： { “realmId”：空 }

这就是他们的示例请求url的样子。如何使用OpenID connect请求索赔
