Ask HN: Has anyone made a web support chat based on Matrix?

Hello,

I've been looking at integrating a support chat into a website (which has live interactions, making a support chat more interesting than support tickets), and I've been thinking that Matrix could be a great system for that.

Has anyone already made some web support chat like this (ie. very simple user popover like interface interacting with a Matrix backend; the operators using a regular matrix client)?
