Thank you. I did finally find that one right after I posted.
As for how to be able to disable the standard interactions with the camera, I found:
how to disable click and drag which mentioned:
viewer.scene.screenSpaceCameraController.enableRotate = false;
viewer.scene.screenSpaceCameraController.enableTranslate = false;
viewer.scene.screenSpaceCameraController.enableZoom = false;
viewer.scene.screenSpaceCameraController.enableTilt = false;
viewer.scene.screenSpaceCameraController.enableLook = false;
