How to activate Authenticator on my new phone without access to my old phone?

Question

I bought a new phone & installed Authenticator on it. And I deleted the original Authenticator on my old phone (without backup). I searched for answers and it seemed that there is no way I can self-help, given that the hole I dug myself into is too deep now.

Can you remove the account associated on the old device and guide me on what is the next step to set up Authenticator again on my new phone?

Thank you.
