Microsoft Graph Security API - Issue with https://graph.microsoft.com/beta/security/tiIndicators

Hi All

I am trying to use Microsoft graph API threat Indicators API based on Azure sentinel recommended way of integrating threat intelligence sources for IOC ingestion to Sentinel Instance. I perform the following steps in linux curl to test the functionality :

• Get the OAuth token from Microsoft using : 

curl -X POST -d 'grant_type=client_credentials&client_id=[myClientId]&client_secret=[myAppSecret]&scope=openid profile ThreatIndicators.ReadWrite.OwnedBy' https://login.microsoftonline.com/[myTenantId]/oauth2/token

• Using the received bearer token calling the following API: curl -X GET -H "Authorization: Bearer [access token]" https://graph.microsoft.com/beta/security/tiIndicators
• I am receiving below mentioned error: 

{
  "error": {
    "code": "InvalidAuthenticationToken",
    "message": "Access token validation failure. Invalid audience.",
    "innerError": {
      "request-id": "########################",
      "date": "2019-12-19T07:41:51"
    }
  }

Anybody has Idea how to use this ? Main motive is to use graph API POST query to insert threat indicators in Azure Sentinel
