How to install python packages like Langchain from internet in Managed notebook without public IP?

[ambeshsingh]

I am stuck in an issue where my managed notebook does not have a public IP and I need to install some packages(like langchain) from the internet.  Any idea how can I let my managed notebook communicate to the internet?

P.S. I am not using Google managed network instead I chose the network in my project and created a private service connection.
