Currently, the B2Qt Demo Launcher (try it on your Android phone from here https://play.google.com/store/apps/details?id=org.theqtcompany.boot2qtlauncher&hl=en) does not have a suitable sample / demo for Industry Automation needs. Please select one of the automation demo's that can be used with B2Qt Demo Launcher (perhaps QTBUG-73022 ?) and update the B2Qt Demo Launcher app.
Optimally this is done in time for Embedded World 2019.
While at it, be sure not to brake
QTBUG-72852 but instead add the Automation demo in to the auto-running demo mode loop.
