Voxelize doesn't generate vox object

Hi! I have been trying to convert gcode to stl with voxelize following the tutorial here: https://voxelizer.com/knowledge_base/articles/360002963734. It seems to working, but when I go to the settings tab where the vox object is supposed to be created, there is nothing there. Am I missing something? Or is this a bug? I’ve tried with multiple gcode files.
