Hi @abhinavohri

Tested this... It looks good so far... Just two things I would change

a) change the icon to the to copy icon
b) change this to a copy action so that a user can just copy and paste the information.

Re-tested works good.

I am wondering if we should also translate the statuses? NEEDS-ACTION (Attendance Response) and REQ-PARTICIPANT (Attendance Requirement)

[kra-mo]

One small thing from the design side is that such a free-floating button should be styled tertiary.

@abhinavohri

Two things,

If you can address the designers comments and make the copied text translated then we can merge the request.
