What is the webhook operator for "is" and "descendants of"


I am trying to create a webhook and I don’t know what is the operator for “is” and “descendants of” :

Thank you for your help!

Instead of doc.shopify_order_id is "set", you can probably just write doc.shopify_order_id. If it has a value, the condition will evaluate to True.

“Descendents of” is more complicated / might not be possible.
