> I also needed to install `gsettings-desktop-schemas` to get the gtk portal to launch.

Thanks for looking into this, it seems thats what I was missing

I wonder why `gsettings-desktop-schemas` is not set as a dependency for `xdg-desktop-portal-gtk`, at least Arch has it set up like that?

Though when trying it for the first time, the file picker opened only after a significant delay, I guess due to this (last line)
```

```

When trying to launch `xdg-desktop-portal-wlr` directly in terminal I get `2023/07/17 20:17:59 [ERROR] - dbus: failed to connect to user bus: No such file or directory`

https://github.com/emersion/xdg-desktop-portal-wlr doesn't list any special requirements/setup, but maybe I'm again missing something here? (eg I don't have pipewire installed)
