Connect to python kernel and virtual environment

[manu0600]

I would like to use iron.nvim with a specified kernel in a virtual environment. I tried already to edit my config as such:

local iron = require("iron.core")
iron.setup {
  config = {
    repl_definition = {
      python = {
        command = "source ~/venv/default/bin/activate && jupyter console --existing",
        type = "bracketed"
      }
    },
  }
}

This technically works, but in the ipython console, I would like to change directory to the current working directory, and also instead of using simply --existing, it would be best if I could spawn a list of the currently available kernels (like the output from ~/.local/share/jupyter/runtime/) and select which kernel to use as --existing kernel-xxxxxxxxxxx.json

Also it would be great from that list to be able to choose "normal ipython" and launch a new ipython window like it's normally done in the defaults of iron.nvim

Could you help me achieve this?
