Remote Gaming On Unraid - Editing XML Assistance Requested

This is really, really niche so I completely understand if no one can help. This is my side project with my spare PLUS license:

 

https://forums.serverbuilds.net/t/guide-remote-gaming-on-unraid/4248/2

I'm stuck on Section 8, part 11:
Each device starts with <hostdev mode=...
and ends with </hostdev>
The black brackets are host devices. There should be one host device for each device we passed through earlier.
The red line is the physical bus, slot, and function the device is assigned.
The blue line is the virtual bus, slot, and function the device is assigned.
Note they are all on the same physical bus (magenta circle)

Coding is NOT my strong suit. Here's my XML file / output and I'm really confused...lost at what parts to edit. I have an AMD 6900XT:
