The title says it all really; Looking for a module that allows a discord bot to communicate with a roblox game instance.
Roblox isn’t designed to be your personal web server. It’s true that you can post a message to discord by using a HttpRequest and a Discord webhook but Roblox isn’t setup to receive requests the other way.
Instead you’ll need to setup your own server to act as a middleman. I see one user has already attempted this using Node: [V2] Discord-To-Roblox Ban bot | 100% Free, End User Friendly & Stable!
For starters, Discord has blocked all requests from Roblox due to people abusing webhooks for logging services, so that completely rules them out.
Additionally, Roblox isn’t designed to accept requests (from outside sources communicating with your Roblox server/game) so what you’re asking for isn’t possible.
I highly doubt that as I’ve seen it done before.
