Discord

Discord is a proprietary, cross-platform, all-in-one voice and text chat application.

Install Discord from the repositories:

pacman -S discord 

Screensharing on Wayland

Currently, it's not possible to reliably share your screen during a call with Discord on Wayland. The current beta builds have support for native screensharing, but sharing audio only works with pulseaudio as the primary sound server.

An alternative client, called Vesktop, has full native support for screen sharing with Discord on Wayland with audio. It can be used instead of the official Discord app.

Install it from the AUR:

yay -S vesktop
