Is it possible to insert various product references into a Various References Collection field at once from the payload on an Automation (On Order Placed)?

Hello All,
I need some help on inserting various References into a single Field in a Collection, originating from a payload on an Automation after a member purchases one or more products.

I’ve tried to call on ‘payload.lineItems.catalogItemId’ but it doesn’t recognize it and I’m not sure how to make an Array of items work with the insertReference function.

I would appreciate if someone could guide me on this as I’ve been searching the documentation and couldn’t see an explanation on it.
Thank you
