Nova
The review queue
Approvals, Nova's drafts, hand-backs and rejection reasons.
The review queue holds everything waiting on a person: campaign steps that need approval, Nova's reply drafts, and conversations Nova handed to you.
Rejecting a draft
Say why: it isn't true, the tone is wrong, or you'll take over. "Not true" moves Nova back to drafts for everyone.
Hand-backs
When Nova hands a conversation to you, you'll see why and a suggested reply. Send your own reply, or let Nova carry on if it was a false alarm.
