DocumentIntelligenceClient is not a function

**Edit 5/24/2024 5:50 PM**
I have tried running the example from the legacy 3.1 documents and do not run into this issue. It seems this is only an issue with the v4.0 documentation.

Output is
`Pages:
- Page 1 (unit: inch)
8.5x11, angle: 0
67 lines, 413 words
Tables:
- Extracted table: 3 columns, 5 rows (15 cells)
- Extracted table: 2 columns, 2 rows (4 cells)`

**Original**
I have tried running the example from the v 4.0 documentation and received this error.
I am running Node 16.13.0 on Windows 10.

I'm not sure what I am doing wrong or if the example has faulty code. Any guidance or resolution would be helpful. Thank you.

Start with the linked v4.0 JavaScript quickstart and compare its DocumentIntelligenceClient usage with the legacy 3.1 example. Reproduce the sample on Node 16.13.0, then update the documentation so the prebuilt model example runs successfully without the TypeError.
