Hey :wave: When should the object be rotated? Only when the user is interacting with it or anywhere on the screen?

when the user click and drag the object itself not anywhere on the screen and as well as rotate it base on mouse position

To handle mouse events on objects: https://engine.needle.tools/docs/getting-started/for-unity-developers.html#inputsystem-callbacks

And then it is matter of saving the drag start position and calculating a delta from that very frame.

Similar to a Joystick logic: https://github.com/needle-tools/needle-engine-samples/blob/main/package/Runtime/FirstPersonController/Scripts/FirstPersonController~/UI%20Components/Joystick.ts
