Virtual Camera Plugin Set Up Help Needed

Hello,
I’m stuck on a part of the documentation to get the virtual camera working.
I’ve been trying to set up a iPad Mini 4 to use it as a virtual camera. Most of the functions seem to work, and when I press play, I can see my desktop Unreal viewport on my ipad, but when I move the ipad around, it doesn’t control the virtual camera.

I enabled all the recommended plugins exept for the “Apple ARKit” which I was unable to find. But I belive it is part of the Unreal Build now, and not a seperate plugin.

I used this Doc tutorial: Virtual Cameras | Unreal Engine Documentation

But I’m stuck on this part here, I’m not sure if this is what is causing my issue. (See Screen Shot)
It says I need to enter what looks like code to the “DefaultEngine.ini file” not sure what, or how to do that exactly.
Any help would be appreciated…Thanks

System:
Windows 10 Pro 64 Bit
Unreal 4.22
iPad Mini 4
