UnknownMethod error in portal on XFCE

[TechnicJelle]

Describe the bug I just heard about this program, and it seems to be exactly what I've been looking for! So I installed it just now, from the AUR and started it up. But it says "Failed to pick a color" in a popup toast message. In the console, it's saying this:

ERROR eyedropper::window > ZBus Error: org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Screenshot” on object at path /org/freedesktop/portal/desktop

I already checked for similar issues, and found #6, #63, and #72, but no solution in there worked for me. I'm on Manjaro XFCE (so X11), and I do have some xdg portals installed:

$ pacman -Q | grep portal
libportal 0.7.1-2
libportal-gtk3 0.7.1-2
xdg-desktop-portal 1.18.4-1
xdg-desktop-portal-gtk 1.15.1-2

Or do I specifically need the gnome one, instead of (or in addition to?) the gtk one?

I can successfully press Ctrl+R to get a random colour, though.

Screenshots

   (The colours on the right are all the same dark background colour. Is that a bug as well? Should I report this in a new, separate issue?) Possibly useful system info:

No, in theory every portal that implements the color picker method should be working. The issue is that your portal does not provide the color picking method.

Yes, but it's most likely caused by your custom theme.

Oh, I see... Thanks for the info. I wonder why it doesn't...

Yes, but it's most likely caused by your custom theme.

Ahh, okay. It's indeed quite likely that I have improperly configured some theme stuff. I've got no clue what I'm doing in regards to theming, haha. I'll look into it.

Thanks for the info! Have a great day! :)
