The fast way: Alert box template
New Overlay → Alert box. That’s it. The overlay comes with an alert widget already placed, listening for follows, subs, cheers, and raids. Click the widget to customize it in the right panel:- Alert image: pick from your media library.
- Alert sound: same, with a volume slider.
- Accent color and seconds on screen.
- Per-event toggles: only want follows and raids? Switch the rest off.
