Good day.
I suggest adding add-ons for the chat.
Namely, translation of the chat in real time into different languages.
For the convenient use of foreign citizens.
So that every Twitch member can customize the translation of the chat text they know.
And also provide the opportunity to select the translation of the chat text separately for the streamer.

How viewers see the chat :
nickname1 - Hello!
nickname2 - Hola!
nickname3 - Привіт!

How the streamer and viewers will see the chat by setting up the translator extension:

nickname1 - Hello! [EU]
nickname2 - Hello! [ES]
nickname3 - Hello! [UA]

Possibly without a letter code at the end.
