You would need to install DisplayLink software to use the Xebec Tri-Screen 2 Adapter. That is a device that plugs into a USB port and provides two second-class, non-hardware-accelerated, video outputs using an interface that seems to have been designed specifically for the Xebec Tri-Screen 2 screen.

The Xebec Tri-Screen 2 Device consists of a pair of "clip-on" 1920x1200 displays. Each has both USB-C and mini-HDMI inputs.

So, as Mr. Bennet-Alder says, if you have a MacBook Pro that has an {M1/M2/M3} Pro or Max chip, you don't need the Xebec Tri-Screen 2 Adapter, or the DisplayLInk software, because your MacBook Pro can directly drive both of the Xebec Tri-Screen 2's screens in a first-class, hardware-accelerated way.
That is, if the 5V 2A per screen power requirement does not turn out to be a deal-breaker. The USB standards only call for a host port to provide up to 0.9A of 5V power on a USB 3 port. Maybe that is why the specs for this device say that it has "2 x USB-C with DP inputs / Video and Power / Pass-through charging" … I wonder if that means that you should plug each of the screens BOTH into your MacBook Pro AND into its own USB-C power source.
