Viewer API - disable panning?

Hi all,

I’m working on a simple Viewer API website to be used in a touchscreen museum kiosk.
Basically, I need to restrict movement as much as possible, the only options the user should have is rotating and clicking the annotations. (so panning and zooming disabled.)

The problem I’m now having is when I click and hold the middle or right mouse button and move the mouse, the camera instantly jumps to what seems to be the centerpoint of the “limit orbit camera”.

Is there a way to completely switch off any panning?
