I don't know of such a solution. However, my own side project / startup ( https://keveo.tv/en/ https://keveo.tv/en/ ) is based on such a concept :) - a website widget where you can immediately initiate a video chat connection with a support agent. It's based on WebRTC, so it doesn't work on iPhones, but it works well everywhere else. If you want to try it out, mail us at info at keveo.tv :) There are several like it, some are free. The best one in my opinion is Appear.in, but they don't provide a widget. Here's a vendor directory: https://webrtchacks.com/vendor-directory/ https://webrtchacks.com/vendor-directory/
