  const handleSend = () => {
    recaptchaRef.current?.open()
  }

  const handleVerify = (token: GoogleRecaptchaToken) => {
    console.log('Recaptcha Token:', token)
  }

  const handleError = (error: unknown) => {
    console.error('Recaptcha Error:', error)
  }

  return (
    <View>
      <GoogleRecaptcha
        ref={recaptchaRef}
        baseUrl="http://localhost:3000"
        onError={handleError}
        onVerify={handleVerify}
