Flatseal and activate permissions

I have found that some versions of certain installed programs, for example "Puddletag", "HomeBank" and "KeePass" but there are more, have the same problem, when trying to open a file from these programs that is on an external device, a hard drive or pendrive, they do not find certain directories on these devices, such as the "media" directory.
The solution has been to install "Flatseal" and activate "All System Files" and "xdg-config/kdeglobals.ro" permissions.
Suggestion: "Flatseal" should come pre-installed in "Zorin OS" and the user should be notified on the presentation page of this problem.
Suggestion: Solve the problem with these problems.
