Ingestion Python - Work for formats other than PDF?

I have the Azure Fn webskill & all other requirements for https://github.com/Azure/cognitive-search-vector-pr/blob/main/demo-python/code/azure-search-vector-ingestion-python-sample.ipynb.

It works fine as long as the docs in the /data/documents sample folder are PDFs. If i put DOCX files in there, the notebook runs but never vectorizes or chunks the content in the DOCX. ??

Open demo-python/code/azure-search-vector-ingestion-python-sample.ipynb from the linked sample and compare its behavior with PDF and DOCX files placed in /data/documents. Run the notebook with a DOCX input and trace the ingestion output; done means the DOCX content is chunked and vectorized consistently with the PDF sample.
