Why this helps
A change of mind can leave an event category inconsistent if a withdrawn decision is not followed by an update.
- Keep a changed decision visible in the event workspace.
- Reduce the memory burden of revisiting withdrawn approvals.
- Tie corrective work to the signal that prompted it.
Setup
Build it in a few focused steps.
- 1Connect Slack and Expofp to Notis once in the portal.
- 2Create an automation through the portal or by asking Notis conversationally.
- 3Use one prompt that asks Notis to update an identified category only when a removed approval reaction accompanies a clear replacement name.
- 4Select the Slack reaction-removed trigger and run-report channel, then test with one real correction.
Questions about this workflow
Will removing any reaction trigger a rename?
The prompt should require the specified reaction and a clear replacement decision in the message context.
Can the action undo a previous update automatically?
No. It updates the existing category to the replacement name provided in the context.
