pip cannot find `pyproject.toml`.

I tried to install with pip install "querychat @ git+https://github.com/posit-dev/querychat#subdirectory=pkg-py", but pip gave a error, saying
ERROR: querychat@ git+https://github.com/posit-dev/querychat#subdirectory=pkg-py from git+https://github.com/posit-dev/querychat#subdirectory=pkg-py does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.

Pip cannot find 'pyproject.toml' in the project root directory.

Please use

pip install "querychat @ git+https://github.com/posit-dev/querychat"
