Download older videos (Spark MP4)

Dear Adobe,

I would like to make a back-up of all the previously made videos.

Adobe Express notified me that I needed to create a folder [Spark video MP4s], but I fail to see how these files can be downloaded.

The following options show: open, change name, delete, place or copy.

The open function doesn't work and placing the file somewhere else or copying the file doesn't resolve my problem.

Please let me know how I can download all the previous videos made in Spark.
