Hi @abhinavohri

Thank you for the PR. But this change will need approval from the design team.

What are your thoughts on this change?

My only comment would be maybe we should make the attachments section collapsible? or list them horizontally instead of vertically to save space.

Hey! Might also ping @kra-mo, any ideas?

I think as far as space concerns go, it might make sense to only show the name and icon if there is a single attachment (or maybe two/three), and without a heading. If there are more, it could just say {n} attachments and show the paperclip :)
