AGOL Jupyter Notebook function signatures

[Theisen]

How do you enable function signatures in AGOL Notebook? I recently came across a video from 7 years ago from ESRI which showed the presenters hovering over their ArcGIS API function and seeing the options they could do with the function. Below is a screenshot. 

I believe these are called signatures. When I press tab, I see something similar but it is more of a list of many different options that is not that helpful. Is this what it looks like currently? 

Appreciate any guidance on this topic. 

Thanks,

In a typical Jupyter Notebook environment, after entering a function name, you can press SHIFT+TAB to view the method's signature. I believe this is what you are looking for.

Pressing TAB by itself is used for autocompletion. For example, after entering an object name followed by a period, pressing TAB will list autocomplete choices for that object.
