Design Mode for constellation apps are deliberately made invisible. Why?
In the App studio header rule to display the "Toggle design mode" button, section Rule: pzComposerBarLeft , design mode button is made invisible for constellation applications (When rule - pyIsConstellationUI).
Due to this, Design mode option is not present in app studio.
Is there a reason for restricting design mode for constellation apps?
Or please correct me & help on how to achieve design mode to configure Actions for constellation apps!
