How do you translate Enrollment Create User ID (from BI Enrollment report) to Username in Learn?

Summary: How do you translate Enrollment Create User ID to Username in Learn? I am trying to determine who created some ILT session enrollments for auditing purposes, but the BI Enrollment Report shows Enrollment Create User ID, which is not an ID that helps me. I am hopeful I can somehow tranlate that to Username. Thanks!
