Access to Metadata from PIXYZ

I am trying to access the Metadata from PIXYZ import using the simple code below. and i keep getting errors.

using UnityEngine;

public class DirectComponentRetrieval : MonoBehaviour
    void Start()
        // Directly retrieve the Metadata component.
        Metadata metadata = GetComponent<Metadata>();

The errors i am getting is:

Assets\DirectComponentRetrieval.cs(10,42): error CS0246: The type or namespace name ‘Metadata’ could not be found (are you missing a using directive or an assembly reference?)

The name of the metadata script as seen on the inspector screen is Metadata.

Can some please help with how to fix this challenge?
