Buffer Attribute Names Export from blender

Hello, I’m trying to set vertex masks in blender to use in three. Everything is working but I’m only able to access the names via color, color_1, color_2 ect… even though I’ve named them differently in blender. Was wondering if anyone would have in insight on how to export so that the buffer attributes have the correct names automatically.

Could you share a .blend file with the vertex masks you’re trying to export?
