IdeaPad S340 w/ ThinkPad USB-C Dock 40A9 compatibility??

The Lenovo sales 24/7 chat specialist assured me multiple times the USB-C Dock 40A9  was compatible with my brand new IdeaPad S340, so I bought one.  However, the dock doesn't power my laptop, nor does it extend display with DP/HDMI/VGA.  It does, however, pick up the sound from the computer.  The firmware update cannot find the dock.  Was the specialist filling me with BS, or is there something special I need to do to get it working?  Or defective?  Thanks for chiming in!

Hi Douglasson! Welcome to our forums community. Unfortunately the device is not compatible to your machine. This is intended for Thinkpad and not Ideapads. You can refer to this link: Hope that answers your question.

Hello! Do you know what device adapter WOULD be compatible to extend the monitor via the usb-c port for the Lenovo S340 Ideapad? I have one monitor plugged into the HDMI and want to plug the second monitor into the USB-c with a USB-c to HDMI adapter. As the gentleman above said, the adapter I purchased from Lenovo doesn't work and I also bought one from Amazon that also doesnt' work.
