Yes, neo is compatible with Barco ClickShare. Just connect with HDMI and USB touchback cable to any of the three HDMI/USB ports and select that source in the float bar/source selection button. You can (optionally) rename that source via the settings menu, submenu General -> Rename Sources to make the ClickShare easier to find for your users.
Note: Running a real time, interactive application (such as a whiteboard) over Clickshare will not be 100% real time. Due to the wireless protocols used in the wireless sharing and touchback, some delays are caused. Still usable, but not 100% fluent.
