Questions about this workflow
What does the trigger provide?
It provides the event ID, summary, start and end times, and organizer information.
Can this calculate meeting hours automatically?
Not from the trigger alone. Ask Notis to store the available times, then calculate duration in a ClickHouse query or provide any additional rules you need.
