Exiting CommandDialog by a user - node.js

Question

I'm trying to find a way exiting a CommandDialog dialog by a user when using back or cancel or otherwise changes their mind.
var startCommands = new builder.CommandDialog();
bot.add('/', [
function (session, results) {
session.send('Hello %s', session.userData.name);
// starting a dialog based on CommandDialog
session.beginDialog('/begin');
},
function (session, results) {
// This is where I want to be when dialog cancel of back is initiated by a user inside /begin
session.send("you are back at the main dialog, start finshing process")
session.beginDialog('/finish');
}
]);
// defining a dialog for CommandDialog class
bot.add('/begin', startCommands)
bot.add('/finish', finishCommands)
startCommands.matches('yo', [
function (session) {
session.send('yo-yo');
}
]);
startCommands.matches('tu', [
function (session) {
session.send('tu-tu');
}
]);
startCommands.matches('.*', [
function (session) {
session.send('any-any');
session.endDialog();
}
]);

To exit a dialog, CommandDialog or otherwise, use a triggerAction on a dialog handler that calls session.endConversation().
For example, here is an exit dialog which ends the conversation when the user sends the message exit or quit.
bot.dialog('exit', function (session) {
session.endConversation('Goodbye!');
}).triggerAction({ matches: /(quit|exit)/i });
