Rails two factor authentication when user signing up with phone number

Question

I have implemented two factor authentication using the following gem.

https://github.com/Houdini/two_factor_authentication

Documentation is simple and clear. This works fine when users tries to sign in. But when signing up the below action in user.rb is not working.

def send_two_factor_authentication_code(code)
end

code in the above is the generated OTP
