My goal is to create a copy of an Experience Builder application (dashboard theme), and update all widgets to reference "test" copies of the hosted feature services/tables. Basically, create a testing copy of the application.
What would be the preferred method for updating the feature service references? I looked at AGO Assist, and there isn't any JSON that displays item ids or widget information, so that is not an option.
My fear is that I will have to build the dashboard from scratch. Someone else built it, and it looks like it took some time (it's a state-level COVID dashboard; just started with org in the fall)
