You need xdg-desktop-portal . Its probably automatic in some environments but with sway I have to set it up manually. Its one of those annoying things I forget about whenever I set up a new machine.

Thanks. On Debian trixie, xdg-desktop-portal-wlr is broken. I had to compile in manually, but this did the trick.
