Custom Notification Sounds Not Updating Without System Restart on macOS

I'm a macOS app developer, and I'm facing an issue with custom notification sounds in my app. After upgrading the app to include new custom notification sounds, the changes do not reflect until the system is restarted. The sounds do not update immediately after the app upgrade.

Is there a way to refresh or reload the custom notification sounds without needing a full system restart? Any guidance or best practices to handle this would be greatly appreciated.

Thank you!
