jupyter on pycharm: the procedure for working on a saved jupyter notebook

Hi.
I am starting to work with Jupyter notebooks and I really love it when it does work. Specifically in pyCharm I love it, although it seems to be difficult to return to an existing notebook.
When I start the notebook on pycharm it raises an alert that asks me for a url and authentication token. it doesn't except the token from when i bash "jupyter notebook list" and i cant access anything on pycharm for all eternity until I forcefully shut it down.
I think my problem is that i don't know how to initialize a url a token when I access the notebook on pycharm.
Is the url generated for for an entire session with multiple notebooks? or does each notebook I open get both?
what is the procedure for working on a saved notebook on pycharm?

No file, test, or entry point is named. First clarify whether the requested outcome is a PyCharm workflow explanation or a Jupyter documentation change, then reproduce the saved-notebook URL and token flow described. Done means the supported procedure and session/token behavior are documented clearly, with the authentication problem resolved or explicitly scoped.
