How to use nox with poetry?

I want to use nox in my project managed with poetry.

What is not going well is that installing dev dependency in nox session.

I have the noxfile.py as shown below:

import nox
from nox.sessions import Session
from pathlib import Path

__dir__ = Path(__file__).parent.absolute()


@nox.session(python=PYTHON)
def test(session: Session):
    session.install(str(__dir__))  # I want to use dev dependency here
    session.run("pytest")

How can I install dev dependency in nox session?
