I need a facebook ads expert

I am starting my own digital ads company. I have one client (Dresswell) and she has given me access to her FB page as an admin. She didn't have a business manager or ad account set up--I went in and did all that and now none of those things are connecting to her page--is it because I set it up under MY account, so its as if I own her ad and business account? I've screenshotted the image of what I have under my accounts. I really just want to start over but I won't even let me remove the account.
