Set up multiple monitors for XRDP (Windows 10 client, Ubuntu 20.04 server)

I am using XRDP to connect to an Ubuntu 20.04 Virtual Machine over a network connection, from a Windows 10 machine. My local setup has 3 monitors, and the VM runs on a server somewhere (Proxmox).

How can I view the Ubuntu VM on all 3 of my monitors?
