Adding calendar events with C# using Google Calendar API

I’m working on a C# project and need help with adding new events to Google Calendar through the API. Right now I can successfully retrieve existing events but I’m stuck on the creation part.

Here’s my current working code for reading events:

using Google.Apis.Auth.OAuth2;
using Google.Apis.Calendar.v3;
using Google.Apis.Calendar.v3.Data;
using Google.Apis.Services;
using Google.Apis.Util.Store;

namespace MyCalendarApp
{
    class CalendarManager
    {
        static string[] AccessScopes = { CalendarService.Scope.CalendarReadonly };
        static string AppName = "My Calendar Application";

        static void Main(string[] args)
        {
            UserCredential userCreds;

            using (var fileStream = new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
            {
                string tokenPath = "access_token.json";
                userCreds = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(fileStream).Secrets,
                    AccessScopes,
                    "current_user",
                    CancellationToken.None,
                    new FileDataStore(tokenPath, true)).Result;
                Console.WriteLine("Token saved to: " + tokenPath);
            }

            var calendarService = new CalendarService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = userCreds,
                ApplicationName = AppName,
            });

            EventsResource.ListRequest listRequest = calendarService.Events.List("primary");
            listRequest.TimeMin = DateTime.Now;
            listRequest.ShowDeleted = false;
            listRequest.SingleEvents = true;
            listRequest.MaxResults = 15;
            listRequest.OrderBy = EventsResource.ListRequest.OrderByEnum.StartTime;

            Events calendarEvents = listRequest.Execute();
            Console.WriteLine("Found events:");
            if (calendarEvents.Items != null && calendarEvents.Items.Count > 0)
            {
                foreach (var item in calendarEvents.Items)
                {
                    string timeString = item.Start.DateTime.ToString();
                    if (String.IsNullOrEmpty(timeString))
                    {
                        timeString = item.Start.Date;
                    }
                    Console.WriteLine("{0} at {1}", item.Summary, timeString);
                }
            }
            else
            {
                Console.WriteLine("No events available.");
            }
            Console.ReadLine();
        }
    }
}

I’m trying to implement something like this for creating events:

var newEvent = new Event();
EventDateTime startTime = new EventDateTime();
startTime.DateTime = new DateTime(2024, 5, 15, 14, 30, 0);

EventDateTime endTime = new EventDateTime();
endTime.DateTime = new DateTime(2024, 5, 15, 16, 0, 0);

newEvent.Start = startTime;
newEvent.End = endTime;
newEvent.Summary = "Meeting with team";
newEvent.Description = "Weekly project update";

// How do I actually save this to Google Calendar?

I’ve been looking through documentation but can’t find clear examples for .NET. What’s the proper way to insert this event into the calendar? Do I need different permissions or additional API calls?
