jsconfig.json intellisense doesn't apply to jupyter notebook code cells

[c3-WesleyPickering]

I am currently looking for a way to modify the JS/TS language server being used in VS Code Jupyter notebook's code cells. In my project I created a jsconfig.json file and included paths to .ipynb and .js files. My intention is to be able to see the same autocomplete and GoTo functionality for the same type in both types of files, however, it currently only works in .js files, whereas the .ipynb files are limited to base js/ts language server intellisense.

Screenshot showing autocomplete for .js file -- UiTestType1 shows up since it is defined in UiTestType1.d.ts.

I would expect the same autocomplete to appear for .ipynb files such as in screenshot below
