I have done it using one of these: (if you find it too expensive, there are cheaper alternatives).

The two HDMI cables from the two monitors go into the adapter and the other side (cable) of the adapter goes into the USB-C port of your laptop.

My laptop is a Dell, older than your Asus - still, when I plugged the adapter, the system automatically recognised the two additional screens and their optimal resolution and I was done in no time. (With three weeks of home office already behind me and at least as much to still come, this has been a life saviour!)
