Need Group Chat with Live Stream Video options

My work just moved all meetings to Slack....what a shame. I really wanted to show off my website and do meetings on it. A great missed opportunity. Rocket Chat aka Chat + is the only thing close yet it seems like it was abandoned by UNA despite being open source. Shout Box isn't a separate mod so that's not an option either. Still no video calling, Live Streaming, or even group chat for JOT. Please UNA many of us have been asking for this feature for over a year and yet nothing. These features are a priority for any website! Rocket Chat is now in 3.0 version but marketplace has only the outdated version from 2018. At least replace it with any new versions. It is also open source so you can modify it using it's code and make a UNA version that supports video chat and group chat. Many people are trying to use it for group chats and realizing the no support for it by UNA. Please take another look at it, update to newest version and make it relevant to UNA again until JOT has a a similar version. No more back burner for group chat, video chat/streaming!
