update/reload jupyter folder

tl;dr: How do I get Jupyter Notebook to "see" newly created notebook without refreshing JN (and then trigger "Token authentication is enabled")?

Details:  I'm new to python and Jupyter Notebook.   Upon starting the Jupyter Notebook, I was greeted with a list of files in the "home" directory on my harddrive. I then moved on to my JN folder, click "new" and then "python 3" to start a new notebook. After I'm done and saved the newly created notebook, I clicked "logout" and closed that tab and returned the initial JN tab. The initial JN tab/folder does not have the newly created file, which is not surprising since it was not there at first. But when I "refresh" the browser I was greeted with "Token authentication is enabled", and I have to go to a terminal and look up the URL, etc.

Question: How can I get the initial JN tab/folder to automatically "see" this newly created notebook without triggering the token authentication business?

Related question: How can I create a new notebook with a specific name, instead of "untitled" and then having to rename it later?

In case this matter, I'm running ubuntu 18.04.

Thanks!
