Missing Prettify button

[Frozenfire92]

I notice in the README screenshot it shows a prettify button (as I see in other graphiql examples like http://try.sangria-graphql.org/graphiql )

However when following standalone example https://github.com/OlegIlyenko/graphiql-workspace#standalone-usage it does not show up. How do I get this?

Hmm it looks like http://try.sangria-graphql.org/graphiql no longer uses graphiql-workspace, it's just a standard graphiql interface. However, a screen shot in README.md still does contain prettify button. When I go to my own instance of graphiql-workspace built with graphiql-workspace-app the button is missing too. Mystery... 🤔
