What are the new acitivites? Where can we see them? Any link?

[Tais993]

Didn't assign "good first issue" for that reason.

Once I have the time to retrieve them I'll update this PR and someone else can try add them if they want ^^

Removed message, see message below for context

Update, found a Gist with more activities.
Seems YouTube Together does work, but has a new ID

Hellooo, may I try tackling this as a first issue?

Hi @Korwai :) Sure thing, thanks for considering. Its been some time this ticket was opened though, so I could imagine that the list of valid activities changed already. @Tais993 do you have an updated list maybe?

[Korwai]

I found this list (https://gist.github.com/GeneralSadaf/42d91a2b6a93a7db7a39208f2d8b53ad) when looking for IDs of VC activities and it seems updated but the one listed in the current documentation refers to this one (discord-jda/JDA#1628).

Any preference on which list I should refer to? ^^

Edit: Never mind, I scrolled up some more and found the same list Tais linked so I'll use that one. xd
