Summary

Updated CloudTrail log examples to clarify user types (IAM user vs IdentityCenterUser) and removed email addresses from userIdentity fields

Security assessment

Changes improve logging documentation accuracy by distinguishing between IAM users and Identity Center users, but there's no evidence of addressing a specific vulnerability. The removal of email addresses from examples demonstrates security-conscious documentation practices.
