Spawn Default Token with Animations

Howdy. I'm using Spawn Default Token to spawn spell effects, but none of the animations are playing when they spawn. Is there any way to change that?

I'm not sure there's any API access for animations yet. Animated images, when spawned instead of dragging and dropping seem to either "break" or default to "stop looping" or default to "pause". I don't think this behavior is unique to SpawnDefaultToken, it's just a limitation of Roll20. It's one of the things, whether anyone at Roll20 has realized it or not, is holding back this system. I've tried creating animated spell effects, for example, using webms and it's just not possible at the moment.

+1 to Timothy's comments. Mod scripts and animations have never played nicely together. It's a Roll20 limitation.
