Concept of Workspace in nvim-dap?

[anunayasri]

Hi. I am using nvim-dap and nvim-dap-python for debugging python projects. The project is a library ie can be imported by python app. The structure is the following -

workspace/
  dvc      << Library
  demo  << demo project to test the library

I am debugging demo and want to set breakpoints in the library codebase dvc. How can I do so using nvim-dap?

In vscode, I am able to add dvc to the workspace and then add breakpoints. Is there a similar concept of workspace in nvm-dap?

Secondly, can I set a breakpoint in a third party dependency? Say I use requests and want to setup a breakpoint in that code. How to do so?
