How to use with DBeaver

Hello,
are there any instructions on how to use this with DBeaver? When I try and add a new client home, I don't know where to search for the client. Looking at the manifest I would expect it at `/app/clients/pgsql/` but DBeaver only shows a file picker without the possibility of manually specifying a path. But since it just uses the file picker from the `xdg-desktop-portal`, I can't browse the files of the flatpak sandbox.
