Create a Teams calendar event from a bot

Trinetra-MSFT Thanks for your response, on jwt.io I could see my permissions, and there was no permission for Calendar. I added it in my app (Azure) and then retried:

 "roles": [
        "User.ReadWrite.All",
        "Group.Read.All",
        "Directory.ReadWrite.All",
        "Directory.Read.All",
        "User.Read.All",
        "GroupMember.Read.All",
        "Calendars.ReadWrite"
],

But with that token I still have the error:

     "The OData request is not supported."

Is "Calendars.ReadWrite" permission the only required? It is without '.All' (like the others), I have not found the '.All' one...

My raw request is:

PUT /v1.0/users/bcb3f5a......23a5925/calendar/events HTTP/1.1
Authorization: Bearer eyJ0eXAiOiJKV1Q.....EUquw
Host: graph.microsoft.com
Content-Type: application/json
Content-Length: 548

{
"subject": "Let's go for lunch",
"body": {
"contentType": "HTML",
"content": "Does late morning work for you?"
},
"start": {
"dateTime": "2020-04-15T12:00:00",
"timeZone": "Europe/Madrid"
},
"end": {
"dateTime": "2020-04-15T14:00:00",
"timeZone": "Europe/Madrid"
},
"location":{
"displayName":"Harry's Bar"
},
"attendees": [
{
"emailAddress": {
"address":"samanthab@contoso.onmicrosoft.com",
"name": "Samantha Booth"
},
"type": "required"
}
]
}

Thanks a lot,
