Estoy tratando de implementar la autenticación de teléfono de Firebase en expo. Firebase está conectado pero me da un error indefinido que no es un constructor (evaluando 'nuevo _auth.PhoneAuthProvider ()')

 //send verification code sms const sendVerificationCode = async () => { try { const phoneProvider = new PhoneAuthProvider(); //giving error here console.log(phoneProvider); const id = await phoneProvider.verifyPhoneNumber( phoneNumber, recaptchaVerifier.current ); console.log(id); Alert.alert("Verification code has been sent to your phone."); navigation.navigate("Otp", { verificationId: id, phoneNumber: phoneNumber, }); } catch (err) { // Alert.alert("Please enter a valid number."); console.log(err); } };
