Domain or one of its subdomains is already managed by Netlify DNS on another team - help needed

Hello Everyone

I tried to host my doradztwostrategiczne.eu site and I did that under my previous account (previous team)
Domain belongs to me - unfortunately I deleted OLD team and created new (by mistake) and now I got this massage: is already managed by Netlify DNS on another team.

I am not good in all this domain settings - so please advice what to do easy way to get my domain back to the existing (new) account. YES, I read docs - and I do not understand this and do not want to mess with server settings.

I did what I was told to do for my domain verification. Is it correct and what are the next steps?
