I need to add co-organizer in teams meeting through graph api

Question

I am using the https://graph.microsoft.com/v1.0/me/events/ endpoint
This is my json code:

{
    'subject': 'Test meeting',
    'body': {
        'contentType': 'HTML',
        'content': 'Group code: Hello'
    },
    'start': {
        'dateTime': '2023-02-25T12:30',
        'timeZone': 'Europe/Sofia'
    },
    'end': {
        'dateTime': '2023-02-25T13:30',
        'timeZone': 'Europe/Sofia'
    },
    'attendees': [
        {
            'status': {
                'response': 'accepted',
                'time': '0001-01-01T00:00:00Z'
            },
            'emailAddress': {
                'address': '
                'name': 'name'
            },
            'type': 'required'
        }
    ],
    'organizer': {
        'emailAddress': {
            'address': 'name@example.com',
            'name': 'Organizer'
        }
    },
    'allowNewTimeProposals': true,
    'isOnlineMeeting': true,
    'onlineMeetingProvider': 'teamsForBusiness'
}

It successfully makes a meeting and adding the participants to it, but I need to assign the participants a role 'co-organizers'. Please help!
