How do I see Web Vitals in the same way as the demo?

In the React project in the Sentry Demo there’s this really nice layout showing the three Core Web Vitals at the top (see first screenshot).

But in our own Sentry (not self-hosted – it’s at https://sentry.io/organizations/<our_org>) we don’t have that view in any of the tabs (All Transcations / Web Vitals / Frontend / …).
The “Display” dropdown also isn’t there.

What do we need to do to get the Web Vitals plots that the demo has?
