You have to download the Jitsi app to use it unfortunately. I saw the video cam icon in UNA messenger, got excited, until it told me to download Jitsi....to me it defeats the purpose since there's no way to avoid having to download it to video chat...I believe Rocket Chat has a built in video streaming service but their website sucks on tutorials and instead refers to Github and special codin...it's really frustrating that a year later and still no video/streaming capabilities. Even Dolphin had tons of native streaming services and video chat options. I would rather have UNA work on that instead of all these other apps
