Locate the Workflow Audit information

Hi, this was already asked in an old post, but there was no solution given.

Where is the Workflow Audit information (like the one in the picture) stored?

For context, I know that Lock History information can be retrieved using the WorkflowLockHistory Data Adapter method, and it's also stored in the WorkflowLockHistory application table.

However, I'm having trouble finding the Workflow Audit information that isn't part of the Lock History. Specifically, I'm looking for details on who performed each workflow step, which is displayed in the workflow audit window but not returned by the WorkflowStatus Data Adapter method. Can anyone provide guidance on where to find this information?
