[Atlas] Access Tracking option not available for M10 cluster

Description

Documentation page https://docs.atlas.mongodb.com/access-tracking/ says that the Access Tracking option is not available on M2-M5 clusters. I have M10 cluster and the option is not available for me. The page does not say what to do to enable the feature.

When I try to use the API I get : 

{ "detail": "Feature not supported by current account level.", "error": 403, "errorCode": "FEATURE_UNSUPPORTED", "parameters": [], "reason": "Forbidden" }
