There should not be a need to do that.
What I did was log in to my school account via the browser on my laptop on office.com or something similar where you have access to your suite of tools, go to your security settings and enable 2FA through this way. The website will or should show you your seed token and it will too ask you to use their own app (don’t!), and once you see it - copy and paste where you want and you should be good to go.
Give it a try right away if you can, it takes a few minutes at most. Let me know how it goes.
If successful, have Ente Auth or Proton Authenticator ready with you to save it there.
