To access the PCD mask (url in the result object), follow these steps :

1. From the "Frames" object, get the "frame_id".

2. Go to "Masks" object, and locate the "frame_id" property with the value needed (from step 1).

3. The "frame_id" property in "Masks" object will have a "label_url" attribute.

4. Use the GET Attachment API with the url obtained from "label_url" attribute.

5. This will generate a Mask file, similar to the sample below.

In the annotation list, each class is associated with a distinct label key, which corresponds to a mask within the array. This label key is aligned with the points in the Point Cloud Data, ensuring that the label key is ordered at the same index as the corresponding point in the Point Cloud Data.
