How do I see changes which a collaborator made with a share link?

There are instructions on how I make a share link but I have not found any instructions on how to view a change made by someone who changed my site through a share link. I asked for help with embedding for custom code, then someone made a fix through the share link. I know he fixed it because he posted a screen shot. When I went into my project it was still unfixed. I looked everywhere in my project settings and I don’t see any obvious way to see his edit.

Share links are read-only. Additionally, editors cannot edit custom code components. So probably no change was made.

You posted a screenshot of the forum working on my page. When I look at my page the forum is not working. How did you get a picture of my forum working as it should?
