Trigger field & criteria to action when a Zoho Books Sales Order is 'packed'.

Hi there.

I'm trying to write a flow that will trigger when a sales order in Zoho Books is packed. The Status field appears to have several status options (i.e. Order, Invoice, Payment and Shipment). When I look at the dashboard, it also shows the order status as well as "invoiced, payment, packed, shipped".

I want to trigger a flow when a sales order (in books) is packed.

Can anybody guide me on what the field & filter criteria would need to be? The "Status" field looks like it shows as Confirmed, until the order is invoiced, packed, shipped and received (at which point it transitions to Closed). I think I need to be accessing a sub status, but not sure how to and what criteria specifically to use.

Thanks in advance.
