how to disable click and drag

How to disable click and drag as it is very frustrating as there is no way to move back to the original map

Hi,
For disable the default event handlers you can use:

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;
