Error that name is already taken

Hi, I know that this is a frequent question, and I went through other responses but I can’t figure this out.
I already told the people who own the domain to set the Nameservers to: dns<1-4>.p02.nsone.net
However, now when I try to add the domain to my netlify account, I get the error

name is already taken, trustblockchainsociety.com is conflicting the ownership with other existing zones

I have checked and I don’t have this domain added to any of my other Netlify sites.

My netlify site url is : tbs.netlify.app
Custom domain i’m trying to add: trustblockchainsociety.com

Any help is appreciated.

Thanks!

The DNS Zone and the site will need to live in the same account, Jon. Our system blocks cross-account usage.

I see the domain as being set up here: https://app.netlify.com/teams/salto-ks/dns/trustblockchainsociety.com

…while the site using the name is in your account here: https://app.netlify.com/sites/tbs/overview

We can, with permission from the domain owner, apply the sitename for you to a site in another team. Let me know if I need to get in touch with Clay to confirm your access.
