There is no license section on https://pypi.org/project/biscuit-python/
https://github.com/dhatim/python-license-check is also not able to retrieve the license
So it seems there is some issue when packaging the license.
What is surprising is that after installing the package in a venv, I can see a license file in .venv/lib/python3.13/site-packages/biscuit_python-0.3.2.dist-info/licenses/LICENSE
