This widget is supposed to show your Twitch followers. But it is very slow because of Twitch API limits. It will work with Twitch authorization script, but we can`t write it by ourselves. You can donate to Twitch authorization script development. About 100$ should be enough. Currently invested 1$, lel.
In OBS you can assign a hotkey to change scenes and show our widgets on them. Go to File - Settings - Hotkeys and bind key to some scene.
To force widgets start when visible, go to layer properties and toggle "Shutdown source when not visible". Widget will start from the beginning every time you show it.
