How to retrieve PHAsset from PHPicker?

PHP Snippet 1:

import UIKit
import PhotosUI
class PhotoKitPickerViewController: UIViewController, PHPickerViewControllerDelegate {
    @IBAction func presentPicker(_ sender: Any) {
            let photoLibrary = PHPhotoLibrary.shared()
            let configuration = PHPickerConfiguration(photoLibrary: photoLibrary)
            let picker = PHPickerViewController(configuration: configuration)
            picker.delegate = self
            present(picker, animated: true)
    }
    
    func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
            picker.dismiss(animated: true)
            
            let identifiers = results.compactMap(\.assetIdentifier)
            let fetchResult = PHAsset.fetchAssets(withLocalIdentifiers: identifiers, options: nil)
            
            // TODO: Do something with the fetch result if you have Photos Library access
    }
}
