Steps to add a new operation to Entity:

- In the entity class:
-- Add definition in handlers/form
-- Override handlers/route_provider with a new route generator.
-- Add route template in links
- Create a new form to manage the operation.
- Generate a new route in the route generator class.
- Add operation in the entity's ListBuilder.
