in apple support

If you want to create a new account then you should be able to do so via this page : https://appleid.apple.com/ - but any content bought/downloaded via an existing account will remain tied to that account (so only that account can download updatwes to its apps).

Or do you mean something else ?

You entire post is "New account".

Do you haev a question?

"New account" is extraordinarly vague/non-descript
