On Yelp how to post review as Business Profile?

Curiously there is nothing for this on the web. None that I could find at least. I have a biz profile (with reviews so I don’t want to mess with a good thing). I also have a personal profile using my real name. Both logins are with the same credentials. I could prob simply change my real name to the biz name but that’s prob not the correct way. I see others suggesting to promote your biz on yelp by giving reviews with your biz name and then maybe this biz would share the love. Anyone have any insight into this???
