What am I missing with Classifiers?

So, I based this project off the work you did on pymdown-extensions. So this is the first project I've actually released with Hatch.

https://pypi.org/project/coloraide/

None of the classifiers are showing up.

I've configured them as dynamic:

dynamic = [
    "classifiers",
    "dependencies",
    "version",
]

And I'm dynamically configuring them:

class CustomMetadataHook(MetadataHookInterface):
    """Our metadata hook."""

    def update(self, metadata):
        """See https://ofek.dev/hatch/latest/plugins/metadata-hook/ for more information."""

        metadata["dependencies"] = get_requirements(self.root)
        metadata["classifiers"] = [
            f"Development Status :: {get_version_dev_status(self.root)}",
            "Environment :: Console",
            "Intended Audience :: Developers",
            "License :: OSI Approved :: MIT License",
            "Operating System :: OS Independent",
            "Programming Language :: Python :: 3",
            "Programming Language :: Python :: 3.7",
            "Programming Language :: Python :: 3.8",
            "Programming Language :: Python :: 3.9",
            "Programming Language :: Python :: 3.10",
            "Topic :: Internet :: WWW/HTTP :: Dynamic Content",
            "Topic :: Software Development :: Libraries :: Python Modules",
            "Topic :: Text Processing :: Filters",
            "Topic :: Text Processing :: Markup :: HTML",
        ]

And yet, they aren't showing up on PyPI. I must be missing a step, what would that step be?

Never mind, it was the same thing I was burned on in pymdown-extensions. I was missing [tool.hatch.metadata.hooks.custom].
