My team mate used netlify for a while. Suppose he has a sub-domain(ok.myfriend.com) pointed to lordest-lain-e289535.netlify.com. He don’t use it it anymore and now he want to let me control. But while i’m doing this i got this error “A DNS zone for this domain already exists under a different account”. A lil bit below i got this too " DNS zones must be unique across Netlify. If you wish to claim the DNS zone for this account, please [contact support]". Could anyone please let me know is this possible to claim this DNS zone record.
