Meeting RSVP Reminder

Steps in this workflow
Send automatic reminder emails to meeting attendees who haven't RSVPed yet. Here's how it works:
- The workflow triggers when a Google Calendar event with guests is approaching
- AI identifies which guests haven't responded to the meeting invite
- Personalized reminder messages are generated for each non-responding guest
- Individual emails are sent asking if they can still attend the meeting
Triggers when an upcoming Google Calendar event is detected, specifically filtering for events that have at least one guest. The trigger activates at the scheduled time using webhooks for instant detection.

Uses AI to analyze the event data and identify guests who haven't RSVPed yet. For each non-responding guest, it generates a personalized reminder message asking if they can still attend.

Processes each guest who needs a reminder by running the email-sending steps in parallel. This ensures all non-responding attendees receive their reminders efficiently.

Sends the personalized email reminder to each guest with the subject "Quick checkin about our meeting later". The email body contains the customized message generated by the AI in the previous step.
