Twitch Achievement?

I got some kind of notification on Twitch today can someone tell me what that means?

There are all possible achievements on Twitch that ensure that you automatically unlock certain things.

e.g. Is there an achievement that you can give the viewers a maximum of 10 VIPS, then one where you can get subscriptions, among other things.
At Twitch there's a tab with "Achievements". There you can see all of them listed, or you can get away with explanations.
I think it's done pretty nicely and it takes a lot of work off the Twitch employees, because everything happens automatically.

OK. Thought that was something to watch or haha … I was really surprised because I don't stream and now I had the absurd idea that my cell phone just picked up 😂😂😂

No, there are many others that are not directly related to streaming.
