Hi and welcome to our community

We've recently migrated Discover's expanded to use EuiCodeBlock https://elastic.github.io/eui/#/display/code
It's a more lightweight component, but offers less features like line numbers

We listen to our users, and here's an issue to discuss how to bring back missing functionality

Expand/collapse JSON in discover

Best,
Matthias
