Zoho Flow - Create Quickbooks Invoice

Zoho Flow - Create Quickbooks Invoice

Hello,

I am looking to create a flow integration between Zoho Inventory and Quickbooks Online and I am not sure how line items are transferred from Inventory to QBO.
I am in Canada so the native integration between Inventory and QBO is not yet available.

In the QBO action "Create Invoice", the fields available to add items are "Sales item line detail value" and "Sales item line detail quantity", to name just two. 
Which available variables from my Zoho Inventory trigger should I use and in which fields  to make sure the invoice is exactly the same in QBO?

The way I understand it, the "Create Invoice" in Flow only allows to add 1 line of item... but all my invoices have more than one item. Also, the variable available from the Zoho Inventory trigger "Line items" seems to regroup all the lines as a single variable.

Best,
