You have to click on the "Invoices" tab, just pick the invoices you want by using the filters. By default, all invoices are diplayed within the pagination you've chosen. By example, if you diplay twenty invoices per page but you have twenty-one invoices in the component, you will have a copy of twenty-one invoices except if you decided to filter as explained before.
Once you decided, you only have to click on the "Download invoices in CSV" link to get the file with CSV extension with all fields for each invoices. If you want a different render just check the documentation for Configuration
