Adding Calendar Event using Microsoft Graph API

I am trying to create an event in a calendar from a Powershell script. It needs to add the calendar event to the organizer's calendar and then to a list of attendees. Below is what I am sending in the body of the request.

{
  "subject": "Let's go for lunch",
  "IsOrganizer": "true",
  "body": {
    "contentType": "HTML",
    "content": "Does noon work for you?"
  },
  "start": {
      "dateTime": "2020-08-31T12:00:00",
      "timeZone": "Pacific Standard Time"
  },
  "end": {
      "dateTime": "2020-08-31T14:00:00",
      "timeZone": "Pacific Standard Time"
  },
  "location":{
      "displayName":"Harry's Bar"
  },
  "attendees": [
    {
      "emailAddress": {
        "address":"[email protected]",
        "name": "Attendee1"
      },
      "type": "required",
       "status": {
                "response": "none",
                "time": "0001-01-01T00:00:00Z"
        }
    },
      {
      "emailAddress": {
        "address":"[email protected]",
        "name": "Attendee2"
      },
      "type": "required",
       "status": {
                "response": "none",
                "time": "0001-01-01T00:00:00Z"
        }
    }
  ],
   "organizer":{
        "emailAddress":{
            "name":"Specific Calendar",
            "address":"[email protected]"
        }
    },
  "allowNewTimeProposals": true
}

It appears successfully on the calendar of the attendees but not on the main organizer's calendar. Can anyone tell me what I am doing wrong and how I can get this to appear on the main organizer's calendar?

Thanks!

UPDATE - This is how I am getting the user token.

$Body = @{
    'client_id' = 'my_client_id'
    'scope' = 'https://graph.microsoft.com/.default'
    'client_secret' = 'my_client_secret'
    'grant_type' = 'password'
    'userName' = '[email protected]'
    'password' = 'password'
}

It is now my understanding that this user should be set as the organizer of an event by default.

You can create an event using ROPC flow which gives you the user access token and using it you can call the /events endpoint with your payload as shown below.

POST https://graph.microsoft.com/v1.0/me/calendar/events

If you create an event with this token and give username as [email protected] this will be the organizer of the event.

And you can update 'subject', 'body/content' but you cannot update the event's 'start' and 'end' properties which is already a finished event.
