Access Teams Attendance using RSC permission

Meghana-MSFT 

Hello. Thank you for your response. The sample you gave is very useful. As you mention this requires the Teams Admin to approve and grant the Graph permission OnlineMeetingArtifact.Read.All - This makes adding the app to Teams a two step process. 1st install the app and then 2nd contact your teams administrator and ask him to give Graph permissions. This graph permission is quite broad giving access to not only the attendance report but also any recordings. Administrators may be weary of doing this.

I had hoped I would be able to gain the attendance report using permissions gained via the Teams App manifest file.
e.g.
{

  "authorization": {
    "permissions": {
      "orgWide": [],
      "resourceSpecific": [
        {
          "name": "OnlineMeetingParticipant.Read.Chat",
          "type": "Application"
        },
        {
          "name": "ChannelMeetingParticipant.Read.Group",
          "type": "Application"
        }
     ]
  }
}

These two permissions should grant me access to the meeting participants. (Using the permissions via the teams app manifest is also more secure as it will only grant access to teams/channels where the app is installed, and in many cases quicker to install as it will allow a user to add the app and make use of its features without involving the Teams Administrator.) However I am unable to find any documentation or samples on how to make use of these permissions?
