USB-C cable type for ZenScreen

[Soundy106]

ZenScreen MB16AMT. I assume it needs a PD-type cable to function? I've used mine interchangeably with the PD cable from my wife's notebook... unforunately she left her cable at the office and has absconded mine and I need to come up with a spare. Using a regular fast-charge USB-C cable results in the monitor connecting and disconnecting constantly even though it has built-in battery power.
