Microsoft graph api ChangeNotification类中未定义活动（问题已由MS支持部门确认）

我正在使用以下测试应用程序检索状态：

在下面的函数中，它接收webhooks回调。它最初执行以下代码来检索纯文本通知：

// The notificationUrl endpoint that's registered with the webhook subscription.
[HttpPost]
[AuthorizeForScopes(ScopeKeySection = "SubscriptionSettings:Scope")]
public async Task<IActionResult> Listen([FromQuery]string validationToken = null)
{

    if (string.IsNullOrEmpty(validationToken))
    {
        try
        {

            // Parse the received notifications.
            var plainNotifications = new Dictionary<string, ChangeNotification>();
            var options = new JsonSerializerOptions
            {
                PropertyNameCaseInsensitive = true
            };
            options.Converters.Add(new JsonStringEnumConverter(JsonNamingPolicy.CamelCase));
            var collection = await JsonSerializer.DeserializeAsync<ChangeNotificationCollection>(Request.Body, options);
            foreach (var notification in collection.Value.Where(x => x.EncryptedContent == null))
            {
                SubscriptionStore subscription = subscriptionStore.GetSubscriptionInfo(notification.SubscriptionId.Value);

                // Verify the current client state matches the one that was sent.
                if (notification.ClientState == subscription.ClientState)
                {
                    // Just keep the latest notification for each resource. No point pulling data more than once.
                    plainNotifications[notification.Resource] = notification;
                }
            }

            if (plainNotifications.Count > 0)
            {
                // Query for the changed messages. 
                await GetChangedMessagesAsync(plainNotifications.Values);
            }

是否有计划将活动和可用性添加到ChangeNotification类中，或者我是否应该坚持解决方案

            string l_szReqBody = await new StreamReader(Request.Body).ReadToEndAsync();
            string l_szDisplay = "";
            dynamic data = JsonConvert.DeserializeObject(l_szReqBody);

            // Verify if the request body is not empty and has json data
            if (!string.IsNullOrEmpty(l_szReqBody))
            {
                JObject body = JObject.Parse(l_szReqBody);
                if (body.ContainsKey("value"))
                {
                    //JValue resource = (JValue)body["value"][0]["resource"];
                    l_szDisplay = string.Concat("WEB HOOK:" + "ID=" + body["value"][0]["resourceData"]["id"] + 
                        ", Activity=" + body["value"][0]["resourceData"]["activity"] +
                        ", Availability=" + body["value"][0]["resourceData"]["availability"]);
                }
            }
