I am trying to add https_url as a source to an existing notebook. It is a simple URL bit I am getting timeout error.

Environment: MacOS
Command: notebooklm source add https://www.geeksforgeeks.org/artificial-intelligence/introduction-to-langchain
Error: 10:53:48 ERROR [notebooklm._core] RPC ADD_SOURCE failed after 30.057s:
Error: Request timed out calling ADD_SOURCE

I didn't find any option to override timeout settings.
