I have the same issue and like another poster, had at one time somehow confused Google with a personal gmail version of an email account that is actually under a Google Workspace account so I get the same choice if G-Suite vs Individual. I've seen it before and worked through it before. I can't see how to make the addin for GWSMO work and the help screen seems to say it won't work for Outlook 365 anyway so I didn't go any farther. I am posting here as I have another email account from the same Google Workspace account (different domain) that works fine and when I update the password for it I don't get the browser doesn't support Javascript error...I get a password field as I'd expect.
Perhaps that will help someone solve the problem for all of us. Meanwhile I'm just using another email client. Once Readdle (Support Ukraine!) gets Spark working in Windows I'll end my 30 year unhappy marriage to Outlook for good. It's always been bloated and difficult software.
