Here is the solution.

Pre-requirement If you want to use the credential in aws-sdk (Manual Process) 1. Create IAM User and Assign a Cognito role to your user. 2. Generate Access Key and Secret Key for that user. 3. Use that Access Key and Secret Key in aws-sdk.

Like This,

let AWS = require("aws-sdk");
AWS.config.update({
    accessKeyId: "YOURKEY",
    secretAccessKey: "YOURSECRET",
    region: "YOURREGION"
});

Create object of CognitoIdentityServiceProvider class

const COGNITO_CLIENT = new AWS.CognitoIdentityServiceProvider({
  apiVersion: "2016-04-19",
  region: "us-east-1"
});


var poolData = {
    UserPoolId: "XXXXXXXXX",
    Username: "kurulezomi@themailpro.net",
    DesiredDeliveryMediums: ["EMAIL"],
    TemporaryPassword: "Abc@321",
    UserAttributes: [
      {
        Name: "email",
        Value: "kuri@themailpro.net"
      },
      {
        Name: "email_verified",
        Value: "true"
      }
    ]
  };
  COGNITO_CLIENT.adminCreateUser(poolData, (error, data) => {
    console.log(error);
    console.log(data);
    callback(null, {
      statusCode: 200,
      body: JSON.stringify(data)
    });
  });

Or else you can directly assign IAM Role to your EC2 Instance in that case you do not need to set credentials in AWS.config Section.
