newThe people who message you can now react from any chat page, including conference rooms and the pop-out view, and every surface displays them.

A reaction pill under a message, exactly as both sides see it
Reactions now work from any chat page: the embed on your site, the pop-out view, the full-page chats, and conference rooms. Every surface displays them, reactions survive refreshes, and tapping one yourself is one click on the message, from a phone or a desktop.
Since the reply feature shipped, press-and-hold on a phone opens reactions and Reply in one menu, and desktop shows them on hover.
