Maybe there’s some way, but Google didn’t want me to know about it. All their docs made it seem like I would have needed to have an enterprise version (no clue what they call it but you know what I mean) of Google services to get it to work, not the free version. I tried for a couple days anyway and couldn’t solve it, so I figured it was a good opportunity to de-google my email. Once I switched to Proton I had it set up in hardly any time at all, and all the different authentication protocols too. Longest part of the process was simply waiting for record propagation.
