Google calendar event notify

[Didgeridrew]

There is another thread on this topic:

How to use Google Calendars' event notification as a trigger and then reference the event in your Actions like you would if you directly referenced it?

So, if I understand the Google Calendar- and the HA Calendar documentation correctly, there’s only a straightforward way to do automations based on when an event starts/ends, but not when its’ notifications trigger, no? I’m asking because I want to mirror those notifications to see them on all devices as soon as they’re created (at the point of the appointment is obviously gonna be too late) and I don’t know how that’s supposed to be possible if the API doesn’t directly include that functional…

TLDR: It’s not reliable.
