Is it possible to get custom attributes on AWS Cognito sign up form?

I am building an Alexa Skill that will implement Account Linking. When a user uses my skill, they would have to use the Alexa App to sign-in.

The Authentication UI is set up and managed by Amazon Cognito so that I don’t have to host my own sign-in and sign-up UI for my Alexa application.

My User Pool in Cognito has two standard and one custom attribute.

The sign-up form (hosted by Cognito) includes text-fields for the standard attributes, but not for the custom attributes. I want text-fields for all attributes (standard and custom). I couldn't find any documentation that shows how to allow this. How do I do it?

I have two standard and one custom attributes. I need all of them from user.

But the sign up form is not showing the input field for custom attribute

According to this documentation, this is not possible. Excerpt from the documentation:

Each custom attribute has the following characteristics:

  • You can't require that users provide a value for the attribute.
  • ...

I was interested too, but i think is not possible using the Login Web Page hosted by Amazon cognito. I've found this information on Amazon Cognito guide: https://docs.aws.amazon.com/en_us/cognito/latest/developerguide/cognito-user-pools-app-integration.html

At the end of this document i've found:

Note

The Amazon Cognito hosted sign-in web page does not support the custom authentication flow.

If i am not mistaken you need to add custom:<YOUR_ATTRIBUTE_NAME> 

var poolData = {
    UserPoolId : <POOL_ID>,
    ClientId : <CLIENT_ID>,
};
var userPool = new AWSCognito.CognitoUserPool(poolData);

var attributeList = [];

var dataEmail = {
    Name : 'email',
    Value : 'email@mydomain.com'
};

var dataPhoneNumber = {
    Name : 'phone_number',
    Value : '+15555555555'
};
var grandMaName = {
    Name : 'custom:grandMaName',
    Value : 'granny'
};
var attributeEmail = new AWSCognito.CognitoUserAttribute(dataEmail);
var attributePhoneNumber = new AWSCognito.CognitoUserAttribute(dataPhoneNumber);
var attributeGrandMaName = new AWSCognito.CognitoUserAttribute(grandMaName);
attributeList.push(attributeEmail);
attributeList.push(attributePhoneNumber);
attributeList.push(grandMaName);

userPool.signUp(userData.Username, userData.Password, attributeList, null, function(err, result){
    if (err) {
        console.log(err);
        return;
    }
    cognitoUser = result.user;
    console.log('user name is ' + cognitoUser.getUsername());
    console.log('Now go to Cognito console and confirm the user.')
});
