Walking around while using the XREAL One + Side View

I was under the impression that some people use their XREALs while walking around by pinning the screen off to one side. Meanwhile, they can see the real world in front of them and safely move around. Is this possible with the XREAL One?

So I haven't managed to do that. When I use Side View, it puts a small screen up in the corner, but the center section of the glasses remains black. (Not sure what is the value of Side View in this case?) When I set the glasses to transparent mode, the entire thing is transparent and there is no view of the screen.

What am I doing wrong? Thank you!
