How to use pick_process API (or otherwise toggle between processes) with nvim-dap and debugpy?

[philippguevorguian]

As far as I understand, nvim-dap has an API for selecting a process in a menu. I've not seen it documented here or used in debugpy configs (only found examples with JS). Is this possible to do? The launch.json I use allows me to start multiprocessing python scripts with modules and correctly represents the state of one of the processes, and I can step over / into on that process until I am sufficiently out of sync with the other process and get an error. So my question is if there is a way already implement to switch between processes or any examples of how to set this up in my nvim-dap configuration?

If this is a more appropriate question for the debugpy repo, let me know. Thanks !
