Unable to open flatpak applications

[SafariKnight]

Trying to open flatpak applications on my system (tested on Hyprland and KDE Plasma) results in absolutely nothing happening.

Doing it from the command line results in this

(I've tested this with multiple apps, same result)

This happens to me too.

I use Sway, so passing it to swaymsg fixes it:
tofi-drun | xargs swaymsg exec --

If I'm not wrong, the solution for Hyprland would be something like this:
tofi-drun | xargs hyprctl dispatch -- exec
