Unbind the domain name with a deleted team

Hello,
I need to regain control of my custom domain name (xiangyuman.com). It was previously used with a different netlify team (may be named ‘clevereggdan’)on my account. But I deleted this team for some reason. I have registered a new domain name and deployed my website successfully using netlify today, but I still want to unbind the previous domain with the team that have been deleted and regain control of it (xiangyuman.com) . The previous team’s netlify site name maybe ‘xiangyuman-hugo.netlify.app’, which is the same as the one I’m using now. I do not want to associate the original domain with the one I’m using and I just want to unbind it with the team that have been deleted.
Thank you for your help~
