Note to readers: you need to view this on a desktop (or maybe a tablet would work?). At least on my phone a considerable amount of the functional UI is completely cut off and rendered inaccessible even with scrolling. (Hopefully they are not dogfooding and this has nothing to do with the tech they’re touting!)
Probably some storybook-related issue, we also use it at work, and while it's a joy to use when it works it can be a pain to set up, and it does tend to need a bit more effort to keep it stable than one would wish for unfortunately.
