For each facet in the configuration, there is a field called display.
Display field is used to indicate what presentation should be for facet within the UI.
Elastic UI Components
If you're using @searchkit/elastic-ui, create a react component to be used for the facet
Then add the facet to FacetsList
Facets component will render all the facets that come back, using the display field to map components with facet response.
