add operation attribute to hydra response

Hi,

Is it possible now to add the operation attribute to your hydra response? It's explained in the hydra documentation: https://www.hydra-cg.com/spec/latest/core/#example-6-a-representation-of-an-issue-augmented-with-a-delete-operation

I've searched the codebase and found that their is a JsonLdContextTrait.php that will add a context, but I couldn't find a trait that adds the operations of the resource to the response.

Thx in advance!
Arne
