Amazon Lex intent - amazon-web-services

Question

I have two intents:
This is the chat bot now:
After this there will be a confirmation whether he wants to invest in equity or not. If he says Yes then another intent must be started without him typing anything.
How do I achieve this?
Here is my Lambda function:
// --------------- Intents -----------------------
var type;
/**
* Called when the user specifies an intent for this skill.
*/
function dispatch(intentRequest, callback) {
// console.log(JSON.stringify(intentRequest, null, 2));
console.log(`dispatch userId=${intentRequest.userId}, intent=${intentRequest.currentIntent.name}`);
const name = intentRequest.currentIntent.name;
// Dispatch to your skill's intent handlers
if (name === 'FinancialType') {
return getFinancialType(intentRequest,callback);
}
throw new Error(`Intent with name ${name} not supported`);
}
// --------------- Main handler -----------------------
function loggingCallback(response, originalCallback) {
// console.log(JSON.stringify(response, null, 2));
originalCallback(null, response);
}
// Route the incoming request based on intent.
// The JSON body of the request is provided in the event slot.
exports.handler = (event, context, callback) => {
try {
// By default, treat the user request as coming from the America/New_York time zone.
process.env.TZ = 'America/New_York';
console.log(`event.bot.name=${event.bot.name}`);
/**
* Uncomment this if statement and populate with your Lex bot name and / or version as
* a sanity check to prevent invoking this Lambda function from an undesired Lex bot or
* bot version.
*/
/*
if (event.bot.name !== 'MakeAppointment') {
callback('Invalid Bot Name');
}
*/
dispatch(event, (response) => loggingCallback(response, callback));
} catch (err) {
callback(err);
}
};
function close(fulfillmentState, message) {
return {
dialogAction: {
type: 'Close',
fulfillmentState,
message,
},
};
}
function elicitSlot(intentName, slots, slotToElicit, message) {
return {
dialogAction: {
type: 'ElicitSlot',
intentName,
slots,
slotToElicit,
message,
},
};
}
function buildValidationResult(isValid, violatedSlot, messageContent) {
return {
isValid,
violatedSlot,
message: { contentType: 'PlainText', content: messageContent },
};
}
function getFinancialType(intentRequest,callback){
var age = intentRequest.currentIntent.slots.age;
var amount = intentRequest.currentIntent.slots.amount;
const source = intentRequest.invocationSource;
if(amount >= 10000){
type = 'Equity';
}
callback(close('Fulfilled',{contentType: 'PlainText',
content: `You have choosen to invest ` + amount + ' in ' + type }));
}

There is an option in the AWS Console for Lex to include a confirmation message. You can ask the user for confirmation there.
