When use type "youtube" response in multiple response like this,
msg.push({
type: 'youtube',
value: 'VIyE2K33w-w',
});
msg.push({
type: 'text',
value: message,
});
it works if it is in the first response.

but any after the second does not work.
msg.push({
type: 'text',
value: message,
});
msg.push({
type: 'youtube',
value: 'VIyE2K33w-w',
});

seems iframe strings might be mis-encoded or not decoded corrrectly. (I might be wrong, sorry...)

Anyway, chatux is so awesome! Thanks!
