how to achive resend OTP using firebase auth

Question

how can Resend OTP after 60 sec. using firebase library, currently using this
https://github.com/firebase/quickstart-js/blob/master/auth/phone-invisible.html

1. called this on first Send OTP

   window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier('sign-in-button', { 
   
   }); 
   

   Working fine its sending first OTP. but i have added timer if 60 sec. cross. it will Resend OTP button

   not its not send Next OTP so how can I achvie That?

2. On Resend OTP click calling Same

   window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier('sign-in-button', { 
   
   });
   

Answer 1

Got the solution: On Resend we don't need to call the same Resend Button Click i.e.

window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier('sign-in-button', { });

instead, we can directly call the inner function

firebase.auth().signInWithPhoneNumber(phoneNumber, appVerifier)

so OTP will be resent.
