Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Related to microsoft sentinel vscode extension that relies on the jupyter extension.

Is it possible to programmatically refresh the kernel dropdown list? It auto-populates with default python3 and users need to manually click the refresh button in the dropdown list for our kernels to pop up.

We retrieve these spark pools server-side and construct the kernelspecs client-side.
