const downloadUrl = await createDownloadUrl(fileStorageProvider, 'reports/annual-report.pdf', userContext);

Creates a pre-authenticated download URL for a file from the specified file storage provider.
This utility function simplifies the process of generating download URLs by instantiating the appropriate storage provider driver and delegating to its CreatePreAuthDownloadUrl method. The returned URL can be provided directly to clients for downloading the file without requiring additional authentication.
