Notifications for followed categories/games

[Avasam]

Since Twitch has no native ways to be notified about followed categories (https://www.twitch.tv/directory/following/games) I am looking for an addon to get notified when someone goes live in a followed category/game. So I can be aware when someone streams a rarely streamed game I'm interested in (often older/more obscure games I speedrun).

So I'd like to request a feature in twitch-live-extension to also show categories.

I found https://github.com/LPauzies/twitch-companion which at least displays followed categories in the popup, but it's FireFox only.
