Is there any way present to import/export app dashboard with custom pages

I am trying to build Grafana App Plugins in Grafana 7.0+, and want to perform some crud operations.
eg: Force delete action: We have custom page present in dashboard with one table for this action we have added button once user will click on delete button, It will open modal to get asset id details, once user put id and click on delete button will call DELETE api call.

So with the above example i want to export this complete app dashboard in another UI. but I’m not able to find out how I can export and import it.
