bot.beginDialog to specific User and Channel - node.js

Question

I'd like my bot to initiate a new conversation with other user at some point in the future. Rather than initiated by incoming POST message as in Bot Connector Node.js documentation, I'm trying to initiate from the conversation itself.
It's not so clear which one is the recommended approach for Node:
Using require('botconnector'),ConnectorClient(), or Bot Connector REST API.
However, based on run-async and LUIS example, I noticed beginDialog actually allows you to specify intended address: bot.beginDialog(address, '/run-async/runner', { name: name }); or cortanaBot.beginDialog({ from: alarm.from, to: alarm.to }, '/notify', alarm);
I thought it's quite straightforward and clearer approach, however, the bot simply stops responding when I include such parameter (It works, if I just use session.beginDialog('/myalarm', { alarm: "some alarm" });). Do I miss out anything?
require('dotenv').config();
var restify = require('restify');
var builder = require('botbuilder');
// Get secrets from server environment
var botConnectorOptions = {
appId: process.env.BOTFRAMEWORK_APPID,
appSecret: process.env.BOTFRAMEWORK_APPSECRET
};
// Create bot
var bot = new builder.BotConnectorBot(botConnectorOptions);
function addressConverter(message) {
return {
to: message.from,
from: message.to//,
// conversationId: message.conversationId,
// channelConversationId: message.channelConversationId,
// channelMessageId: message.channelMessageId
};
}
bot.add('/myalarm', function(session) {
session.send('My Automatic Message');
session.endDialog();
});
bot.add('/', function(session) {
session.send('Hi');
// Delay sending the reply for 5 seconds
setTimeout(function() {
session.send({ text: '5s Time out!' })
var address = addressConverter(session.message);
console.log("Message Address:")
console.log(address)
session.beginDialog(address, '/myalarm', { alarm: "some alarm" });
}, 5000);
session.send({ text: 'I will automatically message you in 5 seconds.' })
});
// Setup Restify Server
var server = restify.createServer();
//server.pre(restify.pre.pause());
// Handle Bot Framework messages
server.post('/api/messages', bot.verifyBotFramework(), bot.listen());
// Serve a static web page
server.get(/.*/, restify.serveStatic({
'directory': '.',
'default': 'index.html'
}));
server.listen(process.env.port || 3978, function() {
console.log('%s listening to %s', server.name, server.url);
})
;
