WooCommerce filter by product > Mailjet

Hi everyone, I’m new here.
I’m trying to set up a scenario in which a person buys a specific product in WooCommerce, and then she’s added to Mailjet, and assigned to a specific group.
I understand I need to set up a filter for WooCommerce, but I can’t find what and how. Basically I need to find an SKU attribute.
E.g. if SKU = 2400, the peron is added as a new contact in Mailjet, and she’s immediately added to a product-specific group there.
(Or, for an existing Mailjet contact, the person’s record is updated by adding her to a new group)

When trying to set up a WooCommerce filter in Make.com, I cannot find the SKU attribute.

Is there a solution?
Thank you
