Question about Sitecom CN 386

My Lenovo E580 has only one USB C 3.0 port. It is charged via the power supply unit. But I can also connect my external touchscreen to it, only then I'm running on battery power. Would it now be possible to use this Sitecom CN 386 part to plug the power supply into the hub and charge the laptop in this way and operate the touchscreen with touch function on another USB C port?
