How use intersphinx_mapping in a directive?

[raybellwaves]

I'm working on rapidsai/cudf#15383 and I would like to know if it's possible to use intersphinx_mapping with a directive?

Currently the project has

.. pandas-compat::
    **DataFrame.query**

I'm not entire sure where pandas-compat is defined but I see "PandasCompat" in the extensions list in conf.py (here)

but I would like to do

.. pandas-compat::
    :func:`pandas.DataFrame.query`

and it creates a link to https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.query.html

I currently get a build error saying

/home/ubuntu/.conda/envs/cudf_dev/lib/python3.11/site-packages/cudf/core/dataframe.py:docstring of cudf.core.dataframe.DataFrame.query:73: WARNING: unknown node type: <pending_xref: <literal...>>
...

FYI pandas-compat comes from https://github.com/rapidsai/cudf/blob/branch-24.06/docs/cudf/source/_ext/PandasCompat.py
