Outline doesn't work on Jupyter Notebooks

[Evileoo]

Describe the bug

When using the default VSCode outline, we can see move into the document.

But Outline Map shows "The active editor cannot provide outline information"

To Reproduce

1. Create a notebook file (extension is .ipynb)
2. write some markdown into it

Expected behavior

I expected to get the same thing as the default VSCode outline

Screenshots

Desktop (please complete the following information):

• OS: Windows 10 Enterprise
• VScode version : 1.80.1
• Outline Map version : 1.3.2

Edit

the outline works only when editing the markdown, and on the part I am editing

Here you can see that my title Aide mémoire VSCode isn't shown but the block I'm editing is.

Moreover, we can see the # characters, it would be awesome if they were not shown

When I use jupyter notebook in vscode, I can only display local functions and variables of the current cell.

On the left : the VSCode default outline
On the right : Outline Map extension

We clearly see the difference
