A minimal switchable Discord RPC feature which will be configureable and hence, like if the player is allowing the RPC perms via an 0Auth2 Authentication then it can have a rich presence like X player is playing on XYZ.xyz or Playing Minecraft on XYZ.xyz and can be toggleable ingame via a command like /drpc toggle or /drpc off or /drpc on.
I can help with the integration if you are not free. ( i might be a noob but eh ...)
