02 Dialogflow CX Messenger vs Legacy Dialogflow ES Messenger

Dialogflow has recently released a new version of the Dialogflow Messenger integration which allows you to add a CX chatbot to your website. I will call this Dialogflow CX Messenger, while I will refer to the previous version as Dialogflow ES Messenger.

Note: these are both terms that I have come up with to distinguish between the two. I don't think the Dialogflow team uses the same terminology. 

I explain the differences between Dialogflow CX Messenger and the Legacy Dialogflow ES Messenger here.
