The following tip in the documentation notes that Grit Studio has a debug button that would allow us to see the AST node associated to some code. This button does not exist as can be noted from the screenshot below.

The link in the tip is https://app.grit.io/studio but we keep being led to https://docs.grit.io/playground instead. Maybe that's the issue?

Is this a paid feature? If so, it's not clear that that's what's going on at all.
