To find machine learning (ML) detections (e.g. crypto mining, anomalous logins), use engine or source filters:
- All ML events: 'engine = "machineLearning"'
- AWS ML detections: 'source = "agentless-aws-ml"'
- Okta ML detections: 'source = "agentless-okta-ml"'
- By category: 'category = "machine-learning"'

You can specify the severity of the events based on the following cases:
- high-severity: 'severity in ("0","1","2","3")'
