How do I keep stdin open when launching an executable via a Desktop Entry File (i.e. .desktop)?

I have a desktop application that relies on stdin. If I run it in the terminal, it runs great and quits when stdin closes (CTRL+D). I also have a systemd activation socket set up which can launch this application. In this case, stdin is connected to the socket and when that socket is closed, the application closes. But when I launch this via /usr/share/applications/*.desktop in gnome, stdin is closed and so the application closes immediately. I see stdin is linked to /proc/12345/fd/0 -> /dev/null. Is there a way to launch an application via the desktop environment so that stdin is open (even if it doesn't have anything writing to it)?
