Please describe your issue in as much detail as possible:

The native file picker doesn't work on Hyprland and possibly other xdg-desktop-portal tasks won't work either. This seems to be because steam supports only xdg-desktop-portal-gtk and xdg-desktop-portal-kde portals but not xdg-desktop-portal-wlr or xdg-desktop-portal-hyprland which Hyprland uses.

Steps for reproducing this issue:

1. Install hyprland, xdg-desktop-portal and xdg-desktop-portal-hyprland
2. Remove other xdg-desktop-portal-* packages
3. Reboot and launch hyprland and then steam
4. Now native file pickers are broken
