### Additional information

Note that in the browser the delete option is there and works for the exact same file

Start by reproducing the issue in the Nextcloud Android app with a file in a folder shared with full add/edit/delete permissions, then inspect the file's ...-menu action handling. Compare the Android menu with the browser behavior for the same file. Done means the delete action appears for eligible shared files and successfully deletes the file.
