AWS cognito users list : lambda - amazon-web-services

Question

I am working on one node application which is using AWS. now i want to get all cognito users but as per doc it returns first 60 users but i want all users. can you assist me with this? In doc, they mentioned that pass PaginationToken (string) . but i don't know what to pass in it.
Here what i have done so far :
exports.handler = (event, context, callback) => {
const requestBody = JSON.parse(event.body);
var params = {
"UserPoolId": "****************",
"Limit": 60,
"PaginationToken" : (what to pass here????),
}
const cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider();
cognitoidentityserviceprovider.listUsers(params, (err, data) => {
if (err) {
callback(null, { headers: { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }, body: JSON.stringify({ statusCode: 405, data: err }) });
} else {
console.log(data);
let userdata = [];
for(let i=0; i<data.Users.length;i++){
// console.log(data.Users[i].Attributes);
userdata.push(getAttributes(data.Users[i].Attributes));
}
callback(null, { headers: { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }, body: JSON.stringify({ statusCode: 200, data: userdata }) });
}
});
};
function getAttributes(attributes){
let jsonObj = {};
attributes.forEach((obj) => {
jsonObj[obj.Name] = obj.Value;
});
return jsonObj;
}

In your response you should see a property called PaginationToken. If you make the same call but include this value in your params you will receive the next 60 users. Here's the concept:
cognitoidentityserviceprovider.listUsers(params, (err, data) => {
// data.Users is the first 60 users
params.PaginationToken = data.PaginationToken;
cognitoidentityserviceprovider.listUsers(params, (err, data) => {
// data.Users is the next 60 users
});
});
You might want to consider switching to promises and async/await if your environment supports it. That would make this code easier to read and write.
const data = await cognitoidentityserviceprovider.listUsers(params).promise();
params.PaginationToken = data.PaginationToken;
const data2 = await cognitoidentityserviceprovider.listUsers(params).promise();
