When linking to option names formatted as code (i.e. using back ticks, like so: xref:mongodb-outbox-event-router-property-route-by-field[`route.by.field`]), the links are not easily recognizeable as such, as they are not in blue color like all the regular links. Only when hovering over the text you'll see that it is a link as the underline is shown them. That's not very user-friendly, as linked option names cannot easily be told apart from non-linked ones.
