Power BI user name, email alias information's on the exported data of workspaces in Admin portal

Unable to identify the owners of Personal workspaces from the Admin portal(Workspaces)

 -User has exported the data from Workspaces from Admin portal.

-Trying to identify the Personal workspace users and their names in the list, however we see there are multiple users displayed with same NAME and we don’t have User name/user email column to identify the user from the data.

For example : Power BI workspace “PersonalWorkspace xxxx”, Searching for workspaces that contains “xxxx” in its name returns multiple personal workspaces.

Expecting the information to be in exported data, so that we can identify which user the workspace is referring to.
