Apple says that to review the app they need sign in info and they only give you the option to input a username and password.
However, in my app you can only sign up with a phone number. What info should I give them?
App Review Information - Sign-In Information with phone
As an option, create a short video that works as demo, then upload it where review can find it and let them know via that app's meta data/review notes.
If they need more info, etc. expect them to reach out.
As a bonus for you efforts, you can perhaps use that clip as a video preview in the store.
I would caution, tho, about requiring such personal info in order to use the app, if in fact that works as a gate to all functions... See the ASRGs/Legal/Privacy 5.1.1 Data Collection and Storage

You can use OTP Widget from MSG91
It support multichannel OTP Verification services. you can send OTP via Email, Sms, WhatsApp, Voice Call etc.
It also has a feature of Demo Credentials where you set a mobile number or email as username and set a fixed OTP for the same which will behave as a password.
This feature is life saving.
