How do I use callbacks on keyframe animations?

[AdamGerthel]

I'm struggling with using callbacks on keyframe animations. For some reason, the callback code either doesn't trigger (version 2.9.1) or causes a crash about trying to run JS code on the UI thread (version 3.0.0-rc.10).

I've tried using both runOnJS and 'worklet' without success.

Here's a snack that uses 2.9.1. I would expect the callback on line 28 to be called when the animation has finished but neither solutions (worklet or runOnJS) seem to work.

What am I doing wrong?
