`xdg-run/pipewire-0` ignores portal permissions from GNOME Settings
The xdg-run/pipewire-0
permission acts as a bypass for portals. Even when the user denies the Camera permission from GNOME, Snapshot still accesses your camera afterwards.
Removing the xdg-run/pipewire-0
permission fixes that issue.
Note: I haven't thoroughly tested this, so we'll have to see if it causes any issues.
