If you didn’t already know, all Episode props (in INK & LL) can be downloaded and used as overlays! On your story go to “PROPS”, tap the little eye, right-click on the prop and save it on your device. It saves as a png so you just upload and use that directly as an overlay.
If you don’t wanna do all that, here all the props in the portal for you to use. I’ll update this whenever they add new props NO CREDIT NEEDED
