QT app start up via systemd

I'm trying to start up QT application via systemd after boot the systemctl status app_startup.service output is:

But running manually the "systemctl start app_startup" cmd it runs perfectly:

Do you have any idea maybe I'm missing some environment definitions?
The .service and run script are attached.

Thanks you in advance, Tanya

I think the issue it is related to permissions since when you are running the command you are ROOT, and when you are using the script your are a local user.
