I played RED on Discord.
2 text channels and one voice:
- #meatspace (for out-of-game chat)
- #edge (for dice rolls and potential in-game text content like prepared datashards etc)
- Agent (for voice)
DiceMaiden bot for dice rolls, and Musify renamed as Johnny Silverhand for ambience
You can look here, Revengeday is cooking up something there
Oh also, there is a "Priority speaker" permission on Discord, might be useful for bigger player groups
