On the manufacturer's page: "The Lenovo USB-C to HDMI 2.0b adapter connects notebooks with USB Type-C ports to display devices that have HDMI ports, such as monitors and projectors. ... take advantage of HDMI 2.0b technology, such as support for resolutions up to UHD 4K at 60 Hz."

So this adapter makes a connection from USB-C to HDMI (out). If an HDMI recording device is connected to it, it should be possible to record the output from the "notebook".
