I was able to add my google account, but the only option I see to add another is "outlook" which I do not have.
Hello.
Check out this article:

For now, Email Protection works ONLY with the following email providers: Gmail and Outlook.
So, it is not possible to get the protection for another email provider, other than Gmail and Outlook.
