USB hub and kvm switch.
Edit: you may also want to get an hdmi splitter (y cable) if your work PC can handle the pixel load so you can get 3 screens for work. I have a link somewhere.

As long as they are active USB-C to HDMI adapters they should work. You might want to get something like this so you still have a free TB port - https://www.amazon.com/gp/product/B0894B525X/
This is the one I got for my two monitors and get 2K@60. I have Windows, not Mac, though. I keep wanting to buy a dock so I don’t tie up a USB-C port for just monitors.
