Read, compose, send, and permanently delete all your email from Gmail (not necessary - I don't use Apple mail on the Mac for access to my Gmail).The pop-up opens safari and takes me to a page that says macOS wants the ability to do all of these (no pick-and-choose possible): 'Google requires completing authentication'.
Now I'm getting a request in Mac OS calendar to enter the password for the Google account. The only previous connection between any Google accounts I have and my Apple world is sharing my Google calendar with my Apple calendar (I can see on all my devices).
