Create Microsoft Teams Meeting invite programatically using graph api - microsoft-graph-api

Question

I am trying to create Teams Meeting invite via graph API but unable to figure out how to send meeting participants via the body as their documentation is not clear. I was using the graph API /me/onlineMeetings as mentioned here with the following body. I am not sure if this is the correct way, All I know is meeting timings, participant email ids. Can someone help me here?
Post request body:
{
"startDateTime":"2021-05-13T10:30:34.2444915-07:00",
"endDateTime":"2021-05-13T10:35:34.2464912-07:00",
"subject":"Testing Invite",
"meetingParticipants": {
"attendees": [{
"mail": "test#outlook.com"
}]
}
}

Answer 1

Yes, you can using graph API.
You need to update your meeting. Please refer to this Update onlineMeeting
You need to update participants property to add/remove attendees.
NOTE You can only modify the attendees field. You cannot update organizer field of the participants property.

Answer 2

To specify presenters and/or attendants please use the below structure.
To find additional information , please refer to the onlineMeeting Properties, and click though to the sub-objects such as attendees.
AFAIK you can not use the API to add presenters / attendees later.
{
"startDateTime": "{{startDateTime}}",
"endDateTime": "{{endDateTime}}",
"subject": "Meeting with {{Attendee_upn}} regarding {{$randomBs}}",
"autoAdmittedUsers": "EveryoneInCompany",
"participants": {
"organizer": {
"identity": {
"user": {
"upn": "jos#jvteams.xyz"
}
}
},
"attendees": [
{
"upn": "{{Attendee_upn}}",
"identity": {
"user": {
"id": "{{Attendee_id}}"
}
}
}
]
}
}
