Zoho Flow - How to consume subarray from webhook

Zoho Flow - How to consume subarray from webhook

I am trying to integrate my ecommerce cart system with Inventory using Flow by receiving a JSON webhook.  Most things are pretty straight forward, however I'm trying to understand how to create a sales order from a transaction that contains multiple items as the items are contained in a subarray.  Here is a snippet of the webhook I receive:

So if I want the customer name I can use ${webhookTrigger.payload._embedded.fx__customer.first_name} to retrieve the first name.  No problem there.

If I want to get the name of the first item I need to use ${webhookTrigger.payload._embedded.fx__items[0].name} by specifying the first position in the items array, but this will only ever retrieve the name of the first item.  How do I write this so that I can get the item name for "n" items?

Thank you for your help!
