Cannot use FBX exported from blender

[JayMcYaru]

It doesn't matter what I do, any FBX exported through blender, regardless of weather the bones are following VRM nomenclature or not, do not work.
If I import a Mixamo FBX and then immediately export the FBX without editing ANYTHING, the model just disappears when I try dragging the FBX into XR Animator.

Are there special export settings I need to use?

XR Animator uses three.js FBX importer, but I have to admit that three.js's FBX support is incomplete and limited. I suppose there should be some settings that can make Blender export work, but unfortunately it's beyond my knowledge.
