How to add new modules on Sphinx?

Question

I'm new to Sphinx documentation. Everything works fine, but I added a new module and it's not being added to the documentation...

conf.py:

# Configuration file for the Sphinx documentation builder.
#
# For the full list of built-in configuration values, see the documentation:
# https://www.sphinx-doc.org/en/master/usage/configuration.html

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join('..', '..', '..')))

# -- Project information -----------------------------------------------------
# https://www.sphinx-doc.org/en/master/usage/configuration.html#project-information

project = 'cludyn'
copyright = '2024, Abel'
author = 'Abel'
release = '1.0'

# -- General configuration ---------------------------------------------------
# https://www.sphinx-doc.org/en/master/usage/configuration.html#general-configuration

extensions = ["sphinx.ext.napoleon", "sphinx.ext.viewcode", "sphinx.ext.autodoc"]

templates_path = ['_templates']
exclude_patterns = []



# -- Options for HTML output -------------------------------------------------
# https://www.sphinx-doc.org/en/master/usage/configuration.html#options-for-html-output

html_theme = 'sphinx_rtd_theme'
html_static_path = ['_static']
