iPhone asks for permission to delete local photos

Hello everyone,
I recently migrated from Android to iPhone.
In general I am using the automatic upload feature as I do not want to have photos stored locally.

On Android everything was working pretty out of the box and Nextcloud was deleting the local photos after a successful upload.

On iPhone I always need to open the app and grant permission to let Nextcloud delete the photos.

Is there any possibility to allow it always without any user request?
