Connect a second monitor z790 proart

Hello, 

Have two monitors with HDMI and Displayport connectors.
I connect the first monitor to HDMI. Where should I connect monitor number two? 
Pc with z790 proart creator Wi-Fi and no separate Graphic card.

I finally understood the Asus manual. I purchased a USB-C to HDMI adapter and plugged into the Thunderbolt port nr1.
Problem solved.
