Help with Appointment reminders using Google Calendar and Gmail

I want to create an automation in n8n, where, once an appointment is scheduled in Google Calendar, 4 emails are sent: one immediately after the appointment is booked, one 5 days before the appointment, one 3 days before, and one 1 hour before the appointment. How can I do this? Also, I want the reminder emails to be written by an AI agent connected to OpenAI so they are personalized.

TL;DR: use registry and a different workflow to process any followups.
