Hey there!

Though we have not yet added support for multiple language tags, we have added more than 350 new options that we think may help out with this particular ask.

For more information, you can take a look at our blog post at https://blog.twitch.tv/en/2021/05/26/celebrate-yourself-and-your-community-with-350-new-tags/. Thank you for your feedback and ideas!

We will leave this topic open for now for further discussion around whether this meets the needs of the request.
