CesiumMan can't walk when using the editor

hey, guys.here take a look at my CesiumMan which is a gltf with animations.I followed https://threejs.org/docs/#manual/en/introduction/Animation-system
but it dont work.

I guess the problem is that the editor does not support SkinnedMesh yet. As soon as skeletons can be serialized, we will make progress in this issue.

three.js R99

Thank you for your help.I’ll keep watching.
