Cannot launch in X11 session

$ echo $DISPLAY
:1
$ cage -- firefox
00:00:00.000 [backend/x11/backend.c:607] Failed to query DRI3 DRM FD
00:00:00.000 [../cage.c:311] Unable to create the wlroots backend

I am using GNOME 45 on X11. This command is run in GNOME Console. According to README, I was expecting it shows a window.

I can use Cage normally in TTY with DRM backend.

Proprietary NVIDIA.
