How to publish and view Wix Sandbox examples?

Question:
When I complete a Wix Sandbox project, how do I view just the page itself that I create with Wix Sandbox? I just finished the sandbox “Recreate a section with grid”. When I published it and opened the URL where Wix said the live sandbox site was published, I see the entire Sandbox lesson instead of just the page that I created. I don’t want to see the entire lesson page, I just want to see what I built. Is this how the Sandbox lessons are supposed to work? Thanks.
