Why this helps
A withdrawal can be acknowledged in chat while the attendee list stays unchanged.
- Keep attendee lists current.
- Reduce manual cleanup after a withdrawal.
- Act on a clear change in availability.
Setup
Build it in a few focused steps.
- 1Connect Slack and ChMeetings to Notis once in the portal.
- 2Create an automation in Automations, or ask Notis conversationally.
- 3Write one plain-language instruction to remove an attendee only when Slack clearly confirms their withdrawal and identifies the meeting and person.
- 4Choose Slack Channel Message Received and the run-report channel.
- 5Test with one real withdrawal for an existing attendee.
Questions about this workflow
Does it remove the person from ChMeetings entirely?
No. The action removes the attendee from a specified meeting, not the person's directory record.
What if the person is unsure?
Tell Notis to wait until Slack clearly confirms they cannot attend.
