如何使用C#在我有写权限的其他用户日历中创建事件？

using Microsoft.Graph;
using Microsoft.Identity.Client;
using System;
using System.Collections.Generic;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        // 配置应用程序的客户端ID、秘密和租户ID
        string clientId = "YourClientId";
        string clientSecret = "YourClientSecret";
        string tenantId = "YourTenantId";

        // 配置其他用户的邮箱地址和日历ID
        string userEmail = "OtherUserEmail";
        string calendarId = "OtherUserCalendarId";

        // 配置事件的详细信息
        string eventSubject = "Meeting";
        DateTime eventStart = DateTime.Now.AddHours(1);
        DateTime eventEnd = eventStart.AddHours(2);

        // 使用Microsoft.Identity.Client库获取访问令牌
        IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
            .Create(clientId)
            .WithClientSecret(clientSecret)
            .WithAuthority($"https://login.microsoftonline.com/{tenantId}")
            .Build();

        string[] scopes = new string[] { "https://graph.microsoft.com/.default" };
        AuthenticationResult authenticationResult = await confidentialClientApplication.AcquireTokenForClient(scopes).ExecuteAsync();
        string accessToken = authenticationResult.AccessToken;

        // 创建GraphServiceClient对象
        GraphServiceClient graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
        {
            requestMessage.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
            return Task.CompletedTask;
        }));

        // 创建事件
        Event newEvent = new Event
        {
            Subject = eventSubject,
            Start = new DateTimeTimeZone { DateTime = eventStart.ToString("o"), TimeZone = "UTC" },
            End = new DateTimeTimeZone { DateTime = eventEnd.ToString("o"), TimeZone = "UTC" }
        };

        try
        {
            // 在其他用户的日历中创建事件
            await graphClient.Users[userEmail].Calendars[calendarId].Events.Request().AddAsync(newEvent);
            Console.WriteLine("Event created successfully.");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error creating event: {ex.Message}");
        }
    }
}
