Opus and Discord

Opus is compatible with Kenku KM—a lightweight, pay-what-you-want application for sharing tabletop audio to Discord.

It’s not needed at all. Sharing the link to your players is easier and gives additional options that Kenku won’t offer, such as allowing players to play their own SFX. If you still want to go that route, Michael made a video to explain how to do it, step by step.
