When looking at this integration https://zapier.com/apps/google-sheets/integrations/magento-v2/16895/create-magento-2x-order-invoices-from-a-google-sheets-spreadsheet, what exactly is going to be created in Magento? Do I need to already have an order and this is just creating the invoice? Is there a sample spreadsheet that could help me get the integration working? I am just trying to understand whats possible here.
