Hi team, how to export data as csv for all charts in a dashboard?\n\nIn apache superset, I see an 'Export CSV' option to export data as CSV for an individual chart. I have a dashboard which has many charts and I want to allow users to export data from all the charts in a single click. What would the easiest approach to achieve the same?\n\nI see the /superset/explore_json?csv=true API can be invoked to export data for a chart. Can it be used for doing same for multiple charts in a single invocation? Or any other better approach?
