Google business account. Which is different than a Google ads account - I was able to get in touch with Google ads support easily but they said the two departments can't talk to each other. It took several weeks to get through to business account support.
Edit: and note, I log into both of these via my personal Google account, which is also a different thing.
What is a "Google maps account"? I have a Google account, which I use with their various services.
