Explanation

This query is looking for anomalies related to suspicious volumes of AWS API calls from non-AWS source IP addresses for a specific user account in each workspace on a daily basis. It excludes any anomalies that are in the "Flighting" status. The query then extends the results to include additional information such as the query details, the number of API calls, the expected number of API calls, and other relevant fields. Finally, it projects the selected fields for further analysis.
