I have the same question :) A USB-C cable is included, but it is only 1m long, so I need a longer one. What I can already say: a USB-C cable with USB 2.0 specification is not enough - the notebook is only charged, but no image transfer etc.. The upstream port on the monitor is specified as "USB-C 3.2 Gen 2" - is a USB-C 3.1 cable also sufficient (as there are hardly any 3.2 cables available)?
