Why this helps
Approvals often sit in chat because no one remembers to turn the signal into creative work.
- Convert a lightweight approval signal into a concrete creative starting point.
- Reduce follow-up messages asking whether the team is ready to proceed.
- Keep the approved discussion connected to its design work.

- 2Create an automation in the portal or ask Notis conversationally for this workflow.
- 3Give Notis one plain-language instruction to create a Canva design when the agreed approval reaction is added to a campaign message.
- 4Select Message Reaction Added as the trigger and choose where Notis reports runs.
- 5Test with one campaign message and the reaction your team uses for approval.
