The USB C cable that comes with the MacBook Pro only supports charging https://www.macintoshhowto.com/hardware/why-your-usb-c-cable-may-not-work-to-connect-you

  It only pretends to be a USB-C cable then.

    Actually, scratch that (can't edit anymore) - looking closer at what you linked to, this appears to be a perfectly fine, data-capable USB 2.0 cable. It's just not a fully featured cable capable of Thunderbolt, and connecting two Macbooks is a feature that relies on Thunderbolt and doesn't work over USB. So, it's just like I said in my initial reply. Really, unless you need to get the highest bandwidth available from latest USB standards, it's not that complicated at all. In most non-Thunderbolt cases, all you need to know is whether your cable is USB 2.0 only or not - and Thunderbolt cables tend to be obviously marked as such.
