Can someone please guide me, how can I create an export action?
As Export Action is not displaying.
You need to save the export action if you want export action to be seen in the Actions panel. The fundamental diff between imports and exports is imports don't need to be saved whereas exports need to be saved.
Go to module ->Data->Export->Rename it-.Save the action
Go to Actions and Put that Export in a Process and publish the process on to the dashboard
Thank you @Misbah.
Very clearly explained. Thanks @Misbah
