Nothing happens when attempting to save folder of photos to photo gallery

Steps to reproduce

1. Navigate to one level above the directory in which the photos you wish to save reside
2. Click "Select" in the upper-right
3. Select the directory whose photos you wish to save
4. Tap "..." in the upper-right
5. Tap "Save to photo gallery"

Expected behaviour

All photos in the directory should be saved to your iPhone's photo gallery, like when you click "Save to photo gallery" with a single photo.

Actual behaviour

Nothing happens.

Logs

If applicable, you can post the iOS app or server logs (removing any sensitive information).

The log is too big to ensure I do not post sensitive information. Sorry.

Reasoning or why should it be changed/implemented?

So people can batch download their photos.

Environment data

iOS version: e.g. iOS 14.8

Nextcloud iOS app version: 4.0.6.0

Server operating system: Ubuntu 20.04

Web server: nginx

Database: mariaDB

PHP version: unknown

Nextcloud version: 22.2.0

No source file or test is identified in the issue. Start by reproducing the folder-based “Save to photo gallery” flow on the iOS app, then trace the existing single-photo save path and determine where directory selection stops being handled. Done means all photos in a selected directory are saved to the iPhone photo gallery without affecting single-photo saving.
