Answer 1

this is the way to works with my code:

 const auth = getAuth(app);
      const appVerifier = recaptchaVerifier.current;
      const fullPhoneNumber = `+${countryCallingCode}${phoneNumber.replace(
        /^0+/,
        ""
      )}`;

      const confirmResult = await signInWithPhoneNumber(
        auth, 
        fullPhoneNumber,

        appVerifier
      );
