Microsoft Authentificator code

Question

Hello, I have a problem logging into my school email, I'm a student and the app where I need this account requires me to change the password and in the process of changing the password it asks for a confirmation code in the authenticator, but the whole problem is that when I try to link an account in the authenticator it asks me for a code in the authenticator app, how will I get the code if I can't even hide the account, what nonsense
