PubSub full documentation
PubSub official documentation only list very few of the topics actually available.
It makes it "officially" not so useful compared to what it can actually do.
Basically it could replace EventSub for most of the cases, and, being far easier to implement would open possibilities for many tools without inducing huge potential server costs.
Is there any plan to document all these topics someday ? Will it remain "unofficial" ?
Have a good day :)
