I'm not sure if anyone other than rylie got it already like few months ago. Few days ago I discovered that connecting to australia using a VPN then refresh Discord using CTRL + R gives you access to Activities beta feature for voice chats like Watch (YT) Together, Land-io, etc.... Not also sure if there are countries outside AUS has this.
You could freely disconnect ur VPN while in Activities feature but you may have to connect it again everytime before refreshing Discord app and connecting to VC again.
