How to export my game as a Discord activity

Godot Version

Godot 4.3 (Stable, Official)
If it’s only possible in Godot 4.4, I can upgrade

Question

If you’ve ever joined a Discord vc, you’ve probably seen these “minigames” that are referred to as activities by Discord. From what I’ve seen, the process to submit one is similar to creating a bot, but there’s not much information online. I already know how to make bots, and I’ve made an app for it (I even saw there were some fields for the activity branding), but how can I actually put my game?
This is an example of what activies are:


I’m guessing I need some sort of webhook, but there is probably some SDK I need to integrate into my game. Could anyone provide me with some guidance? I’ll gather all info collected into this post.
Also, I do not mean a Rich Presence. I’ve seen that there are already plugins for that. I also saw there’s an option to create quests, so if anyone also knows how to do that, help is appreciated. My main question here are activities though

I am preferably looking to do this with gdscript but if it’s only possible using C++ I can use it.
Thanks for your time!

Discord has documentation on it: Discord Developer Portal

Yes but I’m looking for a more Godot based approach here

Bump, this only got 29 views

found this tutorial https://www.youtube.com/watch?v=DvdTvC-lvSc
and this for the sdk, might be outdated though GitHub - 3ddelano/discord-game-sdk-godot: Unofficial Discord GameSDK wrapper for Godot Engine 4.x (includes demo project)
