UI Can't be Unhidden after Hiding

I was entering the Dashboard for the first time, and there was what seemed like a step by step walkthrough of creating a post or connection (not the Let’s Get Started tutorial - after completing that), but I hit “Hide“ and the UI disappeared and I can’t unhide it, so I’m not sure what I’m missing out on or how to get back to that page. I tried refreshing, logging out and coming back, but it doesn’t seem to reappear. The Hide button and content WAS in the area shown in the screenshot.
