Launch a PixyMon in iframe on node red dashboard

Hello there, and I hope all of you are fine.
I have pixy camera with robot. The software for this camera is on the local disc and it works on ubuntu gnome terminal without any problem. the matter I want to start this software from a button on node red dashboard. I tried many times without success. I have even used exec node with python and sh file in order to launch the pixymon file as command from the dashboard but doesn’t work. Dear colleagues, if any solution is available, please i’m in need in my study. Thank in advance
