    Security Note: This toolkit provides code to control a web-browser.

    The web-browser can be used to navigate to:
    
    - Any URL (including any internal network URLs)
    - And local files
    
    Exercise care if exposing this chain to end-users. Control who is able to
    access and use this chain, and isolate the network access of the server
    that hosts this chain.
    
    See https://docs.langchain.com/oss/python/security-policy for more information.
