HI@Gasser23, Welcome to the HP Support Community!
understand that you would like to connect the external monitor using the USB port.
It states on your computer's Specifications page that the USB-C port is: UUSB-C 3.1 Gen 1/DisplayPort (Power Delivery, Sleep & Charge)LAN
You can try using a docking station or you can purchase the routers.
You could purchase the part from HP, use the HP Parts surfer to identify the part: http://partsurfer.hp.com/search.aspx
And order it via the HP Parts store: https://parts.hp.com/hpparts/CountryChoice.aspx?mscssid=&ccode=ZZ&lcode=ZZ
Or alternatively, Contact HP for setting up an order/service via phone support
Hope this helps! Keep me posted.
