Please add proposed API for opening a new notebook that uses a specific kernelspec on a specific kernel

[gjsjohnmurray]

To visualize my goal, imagine adding "Create Interactive Window" and "Create Jupyter Notebook" buttons on the Kernel Specifications rows of your Jupyter Powertoys extension:

I know the baseUrl of the kernel and the name of the kernelSpec but what I need to pass to your openNotebook function (currently defined in api.unstable.d.ts) is the id of the matching internal kernelConnectionMetadata item. Per the discussion in #16221 you do not want me to go via getKernelService (also unstable API) to obtain kernelConnectionMetadata.id

@gjsjohnmurray would adding this functionality in the powertoys extension be sufficient?
Or did you want to utilize such an API in your extension?
Please could you share the use case or scenario? thanks

I work on the InterSystems Server Manager extension which lets users of the InterSystems IRIS platforms browse their server definitions and open workspaces onto them. I want our Jupyter Server Proxy extension to be able to contribute an action button to namespaces on servers in the Server Manager tree, allowing a user to quickly create a new notebook into a namespace.
