Getting access to expressJS request object inside configureScope()

I’m using Express on NodeJS and trying to capture the user information for all sentry events using Sentry.configureScope(callback). From the node docs here, I understood how to set the user using scope.setUser from inside the callback. But the docs just show how to set the user if the email is a hard coded string value. In my case, the user info is stored in the Express request object. So inorder to call scope.setUser with the email, I need access to this request object. Is there anyway I can get access to the Express request object in the configureScope callback?
