Kiwix reads external drive as having no available storage #15

[kelson42]

From flathub/org.kiwix.desktop#15

Trying to download any source from the flathub Kiwix app to a folder on a separate drives gives Storage Error: The system does not have enough storage available. My system is running an immutable Fedora distribution, Kinoite. Could this be a permissions issue, possibly fixable using something like Flatseal to modify Kiwix's given permissions?
