My application supports, under Wayland, both ways of taking screenshots, the KWin and XDG Portal. Both seem to be broken at the moment but adding X-KDE-DBUS-Restricted-Interfaces=org.kde.kwin.Screenshot to the xdg-desktop-portal-kde desktop file as Jan suggested, seems to fix the XDG Portal screenshots at least.
Do I understand correctly that you will fix this so far that we don't need to manually add entries to the xdg-desktop-portal-kde desktop file? Also, KWin Screenshots, like done by Spectacle, are not going to be available to non KDE Applications anymore?

This patch is to lift the For Wayland, I recommend using xdg-desktop-portal standard API to use a portable durable standard API. I am fixing its support in https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/32 I thought it had already been done, sorry for this. And if this does not fill your need, well, do the same as https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/32 in your application. But this screenshot API is not meant to last very long, as this is not Wayland worthy security-wise. This would need better standardisation for instance a Wayland Protocol ideally. Sorry for caughting you unaware.
