Not able to select the scope for spark-compliance:events_read

[testapi334]

I have tried Oauth Integration and provided the scope for spark-compliance:events_read . While getting the access token I am seeing that the scope is only for "scope": "spark:kms". After logging in I am not able to see an out of office dialogue box listing the scope, instead i am getting this :

Is it because I am using a free version ? Are some of the scopes only available for the paid version ? Can someone please help me to resolve this ?

The compliance scope can only be assigned to users with the Compliance Officer role in their org. Free accounts do not have access to this. If you wish to test this you can create a sandbox org using the link on https://developer.webex.com/docs/developer-sandbox-guide and that would give you the ability to assign the CO role to user in the sandbox org.
