Trigger
Channel Message Received

Action
Remove Subscriber

Why this helps
A specific list change can remain pending when the request is buried among unrelated work.
- Complete a specific, confirmed removal request.
- Reduce lingering list-maintenance tasks.
- Keep the request and its run report connected to the Slack handoff.
Setup
Build it in a few focused steps.
- 1Connect Slack and Doppler to Notis once in the portal.
- 2Create the automation in the portal or ask Notis plainly to remove a confirmed subscriber from a Doppler list.
- 3Require explicit confirmation plus an identifiable subscriber and list; instruct Notis to skip ambiguous requests.
- 4Select Slack Channel Message Received as the trigger and choose where run reports should go.
- 5Test the instruction with one confirmed removal request and verify the result.
