how to write a utility class that will read app conifgs using configparser library

I'm trying to create a Python utility class that reads application configurations using the configparser library.

I want the class to:

Load values from a .ini config file

Provide easy access to different sections and keys

Handle missing keys or sections gracefully

Possibly support default values

I'm not sure what the best structure or design pattern for this utility class should be.
How should I implement a clean and reusable utility class for reading configs with configparser?
An example implementation or recommended approach would be helpful.
