Chat with RTX failes to load PDFs - error: PyCryptodome is required for AES algorithm

I put some PDFs in a folder and selected it, but if failed on loading all of them with:
Failed to load file C:\Users.… file.pdf with error: PyCryptodome is required for AES algorithm. Skipping…

I’m guessing I need to install PyCryptodone. How do I do that for the Chat with RTX environment?
I can cd into C:\Users\user\AppData\Local\NVIDIA\ChatWithRTX\env_nvd_rag and run

pip install pycryptodome==3.15.0

will that do it? (I’m not too familiar with Python in Windows)

Thanks.
