Apple's Calendar app has had an API for adding video call links to events for years now, but it is a bit squirrelly, and Google/Zoom can't be bothered to integrate with it. So, instead of just trying to make all my work meetings use FaceTime, I made an app to provide plugins for Calendar.app and integrate against Meet/Zoom APIs. I've taken a couple of looks at this previously, but actually built it this time and got it through Google and App Store review. Still waiting on Zoom review (that'll be v1.1). Does exactly what it says on the tin and no more. Hoping there are still some other macOS Calendar.app users out there to appreciate this.
