Get random document in Sanity.io with the Structure Builder

Content maintainability is hard. One way that you can improve this process is by re-surfacing old content to editors for review.
In Sanity, a quick way to do that is to add a menu item that displays a random piece of content, which is what this video covers.
Get the code for this example in my website: hdoro.dev/random-document-san...
Over the course of the next months I'll try to share other examples of how the structure builder can be used to create effective editing environments. My goal is to show how Sanity can make content maintenance easier (or "Content Ops" in general).
