## Additional Notes
While implementing this feature, I identified and resolved a bug in the `footer.jsx` file that was causing runtime errors. The issue stemmed from incorrect imports from the `react-icons` package, which had been added as a dependency. To maintain consistency with the existing codebase and eliminate the unnecessary dependency, I refactored the imports to use the Lucide icon library that's already integrated into the project. But I couldn't find discord icon in lucide.
