About the camera of Holorens 2

I'm now using hololens2 to create an application that places a virtual light source in the corresponding Unity space when the light source is in the field of view. At that time, I thought it was necessary to know the resolution and focal length (or angle of view) of the camera.

I found out that the application can access the byte data by taking a picture by the method shown in the URL below.

I also found that the resolution of the photo was 3904 x 2196. However, I didn't know about the focal length (or angle of view) of the camera. Can anyone tell me the focal length (or angle of view) of the hololens 2 camera?

Also, since the hololens2 camera is embedded a few centimeters above the hololens2 display, should we assume that the camera is a few centimeters above the Unity main camera in the Unity coordinate space? Also, in that case, how many centimeters is appropriate?

I would appreciate it if you could answer.
