Environment data

iOS version: ipadOS 16.1.1

Nextcloud iOS app version: 4.5.5.2

Server operating system:

Web server: Nginx

Database: MySQL

PHP version: 7.4.3

Nextcloud version: 24.0.7

Reproduce the flow on iPadOS 16.1.1 by opening a Collabora presentation and using the Present button. Start with the iOS presentation-mode flow and inspect the WOPI/download request shown in the logs; done means the presentation opens in presentation mode instead of prompting iOS to handle a downloaded file.
