How do we use this module?

How do we use this module? It isn't explained on the project page and there is no README file.

The README file in progress at https://www.drupal.org/project/date_filter/issues/3339097 📌 Missing README.md file RTBC does not explain how to use the module. It says "After adding the Views Date Filter..." without explaining how to add the Views Date Filter.

How do I add a "Views Date Filter" to a view? After enabling this module, where should I expect to see the "Views Date Filter" in the GUI for my view's settings?

Thank you for your help.
