3D-Panel HoloLens 2 distance

I am working on a HoloLens 2 Experience. In this experience I want to implement some kind of menu. This menu should display buttons and diagrams. The 3D Panel is perfect, but as soon as you bind it to the viewing area, it is so far away.
How can I reduce this distance? I found the binding targets Snap distance (m) and Offset but how do I apply them?
