Expression to hide field on performance document

Summary: If a specific performance document name is being used (Intern Review), we do not want to hide the Manager rating field. Otherwise, we want it to be hidden.

Content (required): We have successfully hidden the manager and associate ratings and scores from the users for all performance evaluations with Page Composer. Since we did that, we found that our intern process needs to have it unhidden to be able to complete a piece of their performance review process. I need to open that field so only the Intern Manager can see it, but I'm finding it difficult to find the statement that will equate to true that will allow the manager rating field only to be open for intern managers and no one else.
