I’ve just had a good look at mine.
I’m not overly familiar with the differences between a regular mk8 and an 8GTI hatch spoiler but the CS one seems to be bonded either side of the standard hatch spoiler retaining the small black aero side wing thingies underneath it and the middle of the CS spoiler is supported by a central sticky down thing which may or may not be bolted (could just be bonded or blu-tacked).
The CS spoiler is in at least three pieces, partly body colour, partly gloss black and the underside seems to be matte black.
I’ll have a proper fiddle with it at the weekend.
