AWS Cognito force refresh session

Question

I'm running into some problems when I attempt to refresh my session tokens, (Access, Id, Refresh). I have already read this question and the answer has helped me understand what is going on some. But I feel what I am trying to do isn't quite what getSession is for.

I am attempting to implement a session expiration message (done) that allows the user to extend their session (refreshes the tokens). From what I gather about getSession(), it returns either the old tokens, if they are still valid, or new tokens if they are not valid. Please correct me if I am wrong there.

I am attempting to give the user new/refreshed tokens every time they click on extend session. For dev purposes, I have a button which then displays the message with the extend session button. The tokens I receive when I call getSession() are the old ones, but I want them to be new ones.

So basically, nullifying the old session and giving them a new one.

My questions are:

1. Am I missing some understanding about getSession(), as previously mentioned?
2. Can I give the user new session tokens (Access, Id, Refresh)?
3. Can I do #2 without having the user sign in again?

Thank you.

EDIT 1: It may help to know that I am not using any Federated Identities.

You can call cognitoUser.refreshSession. I've found a reasonable example for you over here:

Look for the method called checkTokenExpiration, it explains perfectly well what you have to do to refresh the session.
