I need rotation function for multiple 3d actors in a button click but for me it is not working i don't know the function get actor by name is not working ?

var rotationSpeed = 0.15; // Rotation speed in radians per frame
var rotationDuration = 1 * 60; // 3 seconds converted to frames (assuming 60 frames per second)
var rotationCount = 0;
var movingTowardsZ = false;
var movingTowardsGround = false;
var objectToRotate; // Define the object you want to rotate

beScript.onStart = function () {
   console.log("Hello, I'm executed at experience start");
   // Example: Retrieve the object you want to rotate by name or any other method
   objectToRotate = this.getActorByName("Cube", true); // Pass "Cube" as a string, check recursively
};

beScript.onStop = function () {
   console.log("Goodbye, I'm executed at experience end");
};

beScript.onClickablePress = function (e) {
   // Trigger rotation when the clickable is pressed
   startRotation();
};

beScript.execute = function (context) {
   // Delay for 10 seconds
   if (rotationCount === 0) {
       if (context.elapsedTime < 20 * 1000) { // 10 seconds delay
           return; // Exit the execute function if less than 10 seconds have passed
       }
       rotationCount = 1; // Set rotation count to 1 to indicate that delay is over
       console.log("Delay over. Starting rotation...");
   }

   // Rotating the object for 3 seconds
   if (rotationCount <= rotationDuration) {
       console.log("Rotating...");
       if (objectToRotate) {
           var rotationVector = new DSMath.Vector3D(0.0, 0.0, rotationSpeed);
           objectToRotate.rotate(rotationVector);
       }
       rotationCount++;
   }
};

function startRotation() {
   // Start the rotation immediately when the clickable is pressed
   rotationCount = 1;
   console.log("Starting rotation...");
}
