Fastpath webchat customize to become responsive

I would like to customize window to become responsive with bootstrap, but I need documentation to do this fatpath update and webchat.

I want to modify these screens below:

Does anyone know how long the documentation is?

How long? That’s all you have, the source and maybe some javadocs in there GitHub - igniterealtime/Fastpath-webchat: Fastpath Web Chat Component

I’m going to check it.
