Matter.Js scaling a sprite (related to other variables)

I'm using Matter.Js for an interactive animation. One feature I'm working on is to scale some of my bodies relative to their distance to the cursor. My issue is that I cannot seem to scale the sprite which covers these bodies. I tried scaling the bodies themselves but the sprite size did not actually change. So I figured I just needed to scale the sprite size. However I can't seem to get any configuration of Matter.Body.set() to make this change. Reading the source I'm not sure it is possible.

The documentation says: "Given a property and a value (or map of), sets the property(s) on the body, using the appropriate setter functions if they exist. Prefer to use the actual setter functions in performance critical situations."

I've tried:

Body.set(body, {
  render: {
    sprite: {
      texture: // url to sprite reset here incase of overwrite,
      xScale: scaleFactor,
      yScale: scaleFactor
    }
  }
});

This just seems to remove the sprite and any other render settings so I see nothing.

I've tried:

Body.set(body, 'render.sprite.xScale', scaleFactor);

This seems to do nothing at all and doesn't change the rendering.

Is it not possible to set the values of the sprite object at any moment other than the creation of the body? Or am I just targeting those values wrong in my function calls?
