Hello @GeorgeP3040 ,
I'd advise following along with this article on updating account ownership. There isn't an explicit "make new owner" button, it's just a matter of:
updating the account's info, especially the account owner's email address
passing the current login info to the new owner, and
resetting the MFA for the account owner login
If the new owner already exists as a user on the account (manager or campaign creator), once they're logged in and have setup their MFA, they can disable their existing Account Manager / Campaign Creator user, if applicable and desired.
The account owner will also probably want to consider updating the login's password, as a general security precaution. If the username is the previous owner's email, then they'll probably want to update that as well.
