Question Instantiated prefab on TrackedImage doesn't play its animation.

I have this code where I spawn a GameObject on top of a TrackedImage, the object has an animation attached (for example, Hammerhead shark should swim), but the animations never get played.

This is the code:

Code (CSharp):

1.   private void UpdateARImage(ARTrackedImage trackedImage)
2.     {
3.         // Assign and Place Game Object
4.         AssignGameObject(trackedImage.referenceImage.name, trackedImage.transform.position, trackedImage);
5.  
6.         Debug.Log($"trackedImage.referenceImage.name: {trackedImage.referenceImage.name}");
7.     }
8.  
9.     void AssignGameObject(string name, Vector3 newPosition, ARTrackedImage trackedImage)
10.     {
11.         if (animalPrefab != null) { animalPrefab.SetActive(false); }
12.  
13.         if (trackedImage.trackingState == TrackingState.Tracking)
14.         {
15.             if (placeablePrefabs != null)
16.             {
17.                 animalPrefab = spawnedPrefabs[name];
18.                 animalPrefab.SetActive(true);
19.                 animalPrefab.transform.position = newPosition;
20.             }
21.         }
22.    }

This is what happens in the game itself:

And this is how my prefab looks like in Unity Editor:

Any help is kindly appreciated!
