I'm a part of multiple organizations that all use Google Calendar (and I use it for my personal calendar as well).
I need a setup so that when I'm booked on one calendar, it makes me unavailable on all calendars. I've tried setting up a Zapier that adds an event to my personal calendar if an event is booked on my work calendar, and vice versa. This resulted in an endless loop where I had auto-events creating auto-events creating auto-events.
Simply put, I'd like to have a way where I can give someone a calendly link (or something similar) that takes into account my availability across my multiple calendars.
