A multi-national company leverages AWS Cloud for its technology operations. As part of their infrastructure, they utilize a substantial number of EBS (Elastic Block Store) volumes and have both AWS Config and AWS CloudTrail activated for monitoring and compliance purposes. A manager attempted to identify the user who created a specific EBS volume by examining the CloudTrail event logs but was unsuccessful in doing so.

As a Developer Associate, what would you recommend as the appropriate solution in this scenario?
