Is the Registration flow required for unlisted apps?

I want to publish an unlisted app for an enterprise audience and would like to know if the registration flow is required.

Since my app will only have features that require log in Apple guidelines say it needs the registration process but to ensure that only desired users will have access I plan to create accounts from outside the app, thus making the registration within the app unnecessary.

Is there any docs, guideline or policy that states that registration is not needed for unlisted apps?
