microsoft graph api - Attendees didn't get any email notifications on calendar event creation

Question

I've subscribed to Microsoft 365 Business Basic and to try using Microsoft Graph API using this account.

So what have I done:

• Go to https://portal.azure.com/
• Create a new app in App Registration
• Choose "Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox) "for supported account types.
• Once the app is created, in Certificates & Secrets, I created a new Client secret (chose never expires)
• Then in App Permissions, I've added Calendars.Read, Calendars.ReadWrite, User.Read.All, OnlineMeetings.Read.All, OnlineMeetings.ReadWrite.All and grant all of them Admin consent

Then to test the create event API.

curl -X "POST" "https://login.microsoftonline.com/<tenant ID>/oauth2/v2.0/token" 
 -H 'Content-Type: application/x-www-form-urlencoded; charset=utf-8' 
 --data-urlencode "scope=https://graph.microsoft.com/.default" 
 --data-urlencode "grant_type=client_credentials" 
 --data-urlencode "client_secret=<client secret>" 
 --data-urlencode "client_id=<app/client id>"

Then, get list of users, to get the user ID

curl "https://graph.microsoft.com/v1.0/users" 
     -H 'Authorization: Bearer <access token>' 
     -H 'Content-Type: application/json; charset=utf-8'

Then, create the event;

curl -X "POST" "https://graph.microsoft.com/v1.0/users/<user ID>/events" 
     -H 'Authorization: Bearer <access token>' 
     -H 'Content-Type: application/json' 
     -d $'{
  "attendees": [
    {
      "type": "required",
      "emailAddress": {
        "address": "teacher@school.com",
        "name": "Teacher"
      }
    },
    {
      "type": "required",
      "emailAddress": {
        "address": "parent@domain.com",
        "name": "Parent"
      }
    },
  ],
  "end": {
    "dateTime": "2021-02-13T17:32:39.636Z",
    "timeZone": "GMT+8"
  },
  "start": {
    "dateTime": "2021-02-11T16:32:39.636Z",
    "timeZone": "GMT+8"
  },
  "subject": "My event",
  "isOnlineMeeting": true,
  "body": {
    "content": "Does this time work for you?",
    "contentType": "HTML"
  },
  "onlineMeetingProvider": "teamsForBusiness",
  "allowNewTimeProposals": false
}'

The response I get seems good (I get the back all the information that I requested along with some other data). I even get the joinUrl that I've tested fine (I can use the link to get into the meeting).

The only problem is that, the attendees didn't get any email notifications. I wonder if the plan I subscribed is the reason?

Thanks
