Domain Verification for https://calculator-mayank-bisht.netlify.app

I tries to add my domain mayankbisht.com on Netlify, which was owned by someone else in the past, but now I have the domain.
It shows the message “mayankbisht.com or one of its subdomains is already managed by Netlify DNS on another team.” Help me verify the domain.

Site name: calculator-mayank-bisht.netlify.app
Site id: 3ced1fa2-21d2-469b-9562-fdf716e86e4d
