Change arm mesh on Leap Collision Character (unofficial plugin)

The unofficial plugin comes with a leap collision character blueprint that uses a basic body. I wanted to change the mesh on the arms so that when the user sees the arms they don’t see just mannequin hands.

I tried retargetting a mixamo character’s skeletal mesh and switching the character to use that mesh, but then the leap hands no longer show up, although they still track the data and work just invisible.

Are there meshes I can place over a basic modular body so I don’t have mannequin arms when using the leap with the unofficial plugin?
