It sounds like you aren't taking advantage of browser profiles properly. I have two Google accounts, one personal and one for work, and they live in two separate Chrome profiles, both of which are always open. On MacOS the shortcut for switching between the two windows (when both are open) is command-`
That's totally missing the point. You shouldn't have to have browser profiles to call somebody on a video app. Most people don't even know how to use them.
The browser profiles are quite necessary for dealing with every other Google product too. Every day I'm using Gmail, Meet, Docs, Sheets, Drive, Keep, YouTube, Search, and more. If I was trying to do this all in one profile I'd be logging out and logging in dozens of times per day.
This isn't unique to Google; it applies to any kind of single sign on with lots of different products. You're always better off maintaining separate browser profiles so you can seamlessly switch between them than forcing everything into a single profile and endlessly logging out and logging in on all these different sites. I used to do this with Facebook too back when I was using a different account for work development.
And there's also the "poor man's" version of this which even many non-technical users know about, which is to use Chrome for one account and Firefox for another.
