Orders GrahpQL API delivery_method query

[StefanosDev]

I am using the Admin API to query a store's orders via GraphQL and I see that the supported filter parameters have some interesting ones, such as "delivery_method" (https://shopify.dev/docs/api/admin-graphql/2023-10/queries/orders)

My question is, how exactly do I use the delivery_method query param in the orders query? I cannnot find an example and the only help I can see below is the generic search syntax for querying.
