Please allow joystick support for this game!

Hi. I'm new user for flatpak. I'm on Fedora 28 X64 bit Cinnamon edition, xorg system.

I installed TORCS & it working very well apart from one thing essential which make it useless for many gamers: there is no support for joystick ! It is due to sandbox profile for this game ! This should be corrected because this game by itself allow for joystick.
