The provided conversion script (https://github.com/googleapis/python-documentai-toolbox/blob/d29ff95742269a95e1e96e047f0fa1268457292a/samples/snippets/convert_external_annotations_sample.py) seems to only support single-page documents. Uploading multi-page documents results in all bounding boxes appearing on the first page in the DocumentAI UI, despite correct page numbering in the annotations. We've tried modifying the config file without success.

Request:
