Making courses visible to only a specific group of users for QA testing

Summary

What is your process to QA courses in OLC?

Hello everyone,

I'm looking for some best practices. What process do you use to upload a course in OLC for testing? I would like to assign it to pilot testers before releasing the course to our catalog, but I don't want to course to be visible before QA and approval. Our current catalog setting is visible to all employees, so I don't want to have it searchable for everyone until the course is ready for release. Thanks.
