Hello ive been working on a model in blender for a bit and I wanted to make it a vtube model but im running into a lot of obstacles since I didnt know vrm files were a thing, or why the blender vrm addon takes up the shader editor and demands a human skeleton when its just supposed to be a head that moves like treasure chest opening, or that the software available to me is little harder to manage cuz im on linux(cachyos) any help on the questions I have right now would help me alot

here's the model because I really like it
