Oh I see the problem now, I didn't implement the plugin commands properly for the MV version (I mostly developed this for MZ, and converted it to MV at the end, I'll get this fixed and updated, thanks for bringing this to my attention).
Ok, I just updated the MV demo project, and it should work properly now. Thanks again!
