I'm 99% sure that the "aluminum" trim does not come separate from the
door handle, and probably the entire panel including handle.
That stinks if the "techs" marred your pretty handle trim.

But we can accomplish the same thing in an equally distracted/careless moment. Gently buff at it first with microfiber and distilled water and see how much you can knock it back. Then look at finding a touchup paint that matches the "aluminum". It shouldn't be too hard to apply just the right amount; you can always wipe it off as you go if you put on too much.
