Looking for a Thunderbolt 3/USB-C switch that can work with the LG Ultrafine 5K

I have a Macbook Pro and a Mac Mini I'd like to be able to connect to the LG Ultrafine 5K. I've had trouble finding any kind of switching solution that supports the resolution and power features. At this point I don't even need extra ports out of the solution (traditional KVM) and would be perfectly cool with just a splitter of the cable since the display has some USB ports already.

This is a real bummer since that display is promoted by Apple itself. I'd really expected a better solution for connectivity. Please tell me there's something out there.
