Show conversations showing "Ooops, no messages here!"

[phpepe]

After initialize the plugin, when trying to access conversations, nothing is shown.
I expected to see a chat windown with an input text and old messages (as the web widget) so my first attempt was calling Freshchat.showConversations().
My simple question is, how can I get a UI were I can see a message text input and a button to send message?
I know there is a Freshchat.sendMessage() available, but that is a low level functionallity which I'm sure you already implemented.

Thanks in advance
