Use Jupyter Notebooks like REPL Extension

I know that Isaac already has a jupyter like environment for standalone applications but I wanted to know if there was any way to use it similar to an extension. I don’t really want to control the entire app like a standalone flow, just interact with it. I found that there was a REPL extension that is similar to what I want but I would prefer to use a notebook style interface instead. Is this possible? Is there anything that exists like this already?

Also, if I it could run in a vscode notebook that would be amazing.
