A watch party allows you to share a stream (YouTube, TikTok, Facebook Live, Twitch, etc.) with the other participants of the call.
This function is currently only available on Google Chrome for now, but other browsers might extend their support for this feature.
To start a new watch party, click on the ‘Share’ button, a popup will open. First select Chrome Tab, then choose the tab in which your stream is playing and finally tick the ‘Share audio’ option.
