cable for docking d6000

I need a new cable for my Dell docking d6000. One plug is broken. The cable has on one side a USB-C right-angled plug and on the other side a USB-C together with USB plug, see picture. The length is about 1 meter. An normal USB-C to USB-C cable does not work. I can not find this cable on the Dell website. How do I become such a cable?
