How to use the @aws-amplify/auth.forgotPasswordSubmit function in @aws-amplify/auth

async forgotPasswordSubmit() {
    const { username, authCode, newPassword } = this.state
    await Auth.forgotPasswordSubmit(username, authCode, newPassword)
    .then(() => {
      this.props.navigation.navigate('SignIn')
      console.log('the New password submitted successfully')
    })
    .catch(err => {
      if (! err.message) {
        console.log('Error while confirming the new password: ', err)
        Alert.alert('Error while confirming the new password: ', err)
      } else {
        console.log('Error while confirming the new password: ', err.message)
        Alert.alert('Error while confirming the new password: ', err.message)
      }
    })
  }
  render() {

return dispatch => {
    if (data.password !== data.password2) {
      dispatch(onAuthError("Passwords do not match."));
      return;
    }
    dispatch(loadingStart());
    Auth.forgotPasswordSubmit(data.email.toLowerCase(), data.code, data.password)
      .then(() => dispatch(setAuthPage("signIn", "Password changed successfully! Please log in with your new password:")))
      .catch(e => dispatch(onAuthError(e.message)))
      .then(() => dispatch(loadingEnd()))
  }
}

submit() {
		const { authData = {} } = this.props;
		const { code, password } = this.inputs;
		const username = this.getUsernameFromInput() || authData.username;
