One question re CopyButton, other than that LGTM!
Sorry, I thought CopyButton is rendered as a child of Button, must be me being not completely awaken 😆

[levadadenys]

LGTM!

nit for the future: (Maybe we already have this in jira) Maybe update the CopyButton to use new DesignSystem Button (for better ui)?

Nice!

Nice! Just to double check are we / @markabarrett okay with the two different button styles (for copy and clear)?

@sanchitmalhotra126 oh the styling is definitely not perfect, I expect we'll continue to iterate/improve here (eg, the header background itself is black here, but gray in the mocks, so we'd ideally restyle the header and also change the color of the clear button as well). The copy button was actually not in the mocks, but Sam suggested we keep it around for the pilot since it already exists.
