How to export/load custom VRMA?

[Benjythebee]

To test importing VRMA animations, I have this FBX boxing mixamo animation.

I transformed it into a VRMA using VRM Addon for blender (blender 4.2)
This is the output: https://github.com/Benjythebee/three-vrm-cache-repo/blob/master/cheering.vrma

Loading the VRMA output into this three-vrm example just doesn't work.

Do you have a way to make advanced animations work as VRMA?

Please add tag "discussion" if possible

For reference, I made an issue in Saturday06's Blender Addon just in case
