Rebuild LiveChat?

I am trying to use the updated LiveChat app. I built the files using the instructions at https://github.com/RocketChat/Rocket.Chat.Livechat and put them in programs/web.browser/app, but I am wondering how RocketChat’s setup picks up the new JS files, index.html, etc to serve this new version? Right now it is serving the version that was in original RC setup. Any help?
