Another Virtual desktop Help Question!

First, thanks for the clear instructions. However, maybe I don’t understand them, particularly part quoted above. I’m able to do all that you state. I have the plane on the runway ready to go, when using Oculus Link, I just hit alt + tab, the display finds my headset and switches to twin views. However, when I am here in VD, I have to shrink down MSFS, go to task manager as you suggest, close Steam VR. When I return to MSFS and press alt + tab, it says “headset not found”. Clearly, I’m missing something.
