How to separate blender Vortex Group/"Outliner Data Operation" from an object?

What the title says, I downloaded a model from the internet, but the legs, arms and torso are in the same object inside of a “Vortex Group” (I have never used blender in my life and i only installed it to try and fix this issue)


As you can see, basically everything is inside of the torso/body model (the head, eyes and hands aren’t, but they can also be seen in the vortex group). I heard about P in edit mode but it’s not working with these vortex things, is there a way to do this?
