Install browser inside LXD container and run it on host OS

I am trying to install Brave browser inside an LXD container (Voidlinux - preferably, or linuxMint), create a shortcut for that app inside my host OS and launch it as any other linux app with the exception that it will run inside a container. I am not sure how to configure the display part or lxc profile on my non-ubuntu host OS. Tries these tutorials with no success: https://blog.simos.info/running-x11-software-in-lxd-containers/ например, environment.PULSE_SERVER: unix:/home/ubuntu/pulse-native connect: unix:/run/user/1000/pulse/native listen: unix:/home/ubuntu/pulse-native what can I replace ubuntu and user with in a Gentoo distro? lxc exec mycontainer -- sudo --user ubuntu --login that isn't working in voidlinux container.
