Action
Create One-Off Event Type
Creates a temporary calendly one-off event type for unique meetings outside regular availability, requiring valid host/co-host uris, a future date/range for `date setting`, and a positive `duration`.
Why this helps
A special session can require extra setup when the standard Calendly options do not fit.
- Handle exceptional sessions without changing the usual routine.
- Create a temporary option for a future date or range.
- Keep one-off meeting logistics tied to the planning thread.

- 3Give Notis one instruction to create a one-off event type when a Slack message clearly confirms a special future session and provides the required meeting details.
- 4Choose the Slack channel message trigger and a run-report channel.
- 5Test with a real, confirmed session request and verify the temporary type.
