    import DragRotateAndZoom from 'ol/interaction/DragRotateAndZoom.js';

Allows the user to zoom and rotate the map by clicking and dragging on the map. By default, this interaction is limited to when the shift key is held down.

This interaction is only supported for mouse devices.

And this interaction is not included in the default interactions.
