Does the iOS gonative.share.downloadImage function cater for video files (e.g. mov or mp4 files)?

I'm attempting to use the iOS gonative.share.downloadImage function for video files. Calling the function does not raise an error but the video is not saved. If I can save videos using the downloadImage function than that would be my preferred option.

Alternatively, I can use the gonative.share.downloadFile function but that does not provide any appropriate "open with" options. Options include AirDrop and OneDrive but I was hoping that "Photo Gallery" may appear as well.

Can you please advise me on the best approach to download video files to an iOS device?

Thanks
