twitch-chest-auto-click.js

// open a twitch channel with channel points
// open chat or popout chat
// open inspector (Opera: CTRL + SHIFT + C, Chrome: CTRL + SHIFT + I, Firefox: F12)
// open console in tab
// copy / paste code + ENTER
// only works if you view a live stream. (just open chat is not enough)
