Can Project IDX run a JavaFX app?

Hi IDX team,

I’m loving Project IDX and all the capabilities that it has; however, I just tried to run JavaFX and I was able to import all the missing packages

pkgs.xorg.libX11 pkgs.xorg.libXxf86vm pkgs.libGL pkgs.xvfb-run

After making the rebuild and running the app again, I’m facing this error:

Caused by: java.lang.UnsupportedOperationException: Unable to open DISPLAY

and I’m wondering if Project IDX has the capability to run that kind of project.
