وعليكم السلام،
bro, great tutorial! However, I have 5 questions, please forgive me:

1. Is OTP highly expensive? Could you provide me with the billing documentation link about it?
2. How did you implement the verification reCAPTCHA on a separate screen (the "I'm not a robot" check) and automate it?
3. In my app, after entering a valid phone number, it asks me to validate reCAPTCHA, then sends OTP, but I haven't received anything. I noticed the phone number verification API only returns session info.
4. What is SMS Multi-factor Authentication under Sign-in providers in Firebase?
5. What is the functionality of "Phone numbers for testing"?
