To allow for testing searches better, we should add a `mockup-response` prop as on [FetchForm](https://github.com/limbo-works/Limbo.Nuxt.FetchForm/blob/0.1.1/components/FetchForm.vue#L42C5-L42C26). This will allow us to test the search before the endpoint exists, as well as test changes to the search before they are added in backend.
