Why this helps
Approved plans can still be hard to scan in long messages and threads.
- Make a lengthy approved brief easier to scan.
- Use a familiar reaction as a lightweight signal.
- Share a visual reference with collaborators.
Setup
Build it in a few focused steps.
- 1Connect Slack and Customjs to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to set it up conversationally.
- 3Ask Notis to render the reacted-to message as a readable image when the agreed approval reaction is added to a brief.
- 4Select the Slack reaction-added trigger and a run-report channel.
- 5Test with one approved brief and check that the text remains legible.
Questions about this workflow
Will it create an image for each reaction?
The instruction should identify the agreed reaction and the message type that should qualify.
Can it preserve section headings?
Ask Notis to retain the source message's headings and structure in the rendered image.
