+   * In the endpoint to retrieve environments from each folder, the environment does
+   * not have the `latest` key and the data is all in the root level.
+   * To avoid doing this check in the view, we store both cases the same by extracting
+   * what is inside the `latest` key.

+   * If the `size` is bigger than 1, it means it should be rendered as a folder.
