how to save video into an User Album with PHPhotoLibrary, PHAsset

Hello,

I want to save the video file into a specific USER Album named "Cambox Album".

Actually only works into the default Album in recent assets with the true new name nameX.mov.

Below the code for define the PathDirectory :

func getDirectoryPath() -> String {

        let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
        let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, .userDomainMask, true)

        let documentsDirectory = paths[0]
        return documentsDirectory

    }    

with this code below, the video is automatically saved in the default user album.

func downloadVideo(urlVideo : URL! ) {

        DispatchQueue.global(qos: .background).async {
            if let url = urlVideo, let urlData = NSData(contentsOf: url) {
                let galleryPath = self.getDirectoryPath()
                let filePath = galleryPath + "/nameX.mov"

              DispatchQueue.main.async {
                urlData.write(toFile: filePath, atomically: true)
                   PHPhotoLibrary.shared().performChanges({
                   PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL:
                   URL(fileURLWithPath: filePath))
                }) {success, error in
                  if success {
                       let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert)
                       let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil )
                       alertController.addAction(defaultAction)
                       self.present(alertController, animated: true, completion: nil)
                   } else {
                       let alertController = UIAlertController(title: error?.localizedDescription, message: nil, preferredStyle: .alert)
                       let defaultAction = UIAlertAction(title: "ERROR !", style: .default, handler: nil)
                       alertController.addAction(defaultAction)
                       self.present(alertController, animated: true, completion: nil)
                   }
                }
             }
          }
       }
    }

if I replace the line with the name of the album by :

let filePath = galleryPath + "/Cambox Album/nameX.mov" nothing happened, I can't see the video anywhere !

is there anybody who can help me to resolve this issue please ?

Regards
