Get TestCase CreatedBy accountId using Rest API

Hello,

I'm using the Zephyr Scale Cloud REST API to extract TestExecution data, which includes TestCase data. I've got all of the data that I need, with the exception of the accountId of the JIRA user that created the TestCase. I have not found any API that exposes createdBy.

The Get Test Case response schema includes the createdOn property, but not createdBy.

The only place I see the CreatedBy property, when I look at a Test Case in the UI, is in the Test Case History, which does not appear to be exposed through the REST API.

Am I missing/overlooking something, or can anyone point me in the right direction, if there is one.
