How to implement browser emulator and use sessions from application?

Question

Node.js

There is an account manager on nodejs for VK, which saves many sessions. I want to do something like a browser in a browser. That is, there is an admin panel and from it I manage accounts, send messages and check, but sometimes you need access to the site from under the account. What can you think of to access the VK site using the sessions from the node under the required account? That is, it will be like a frame that leads to the VK site, but with the session I need.
