BackbonePluginConfiguration - How to configure in pom.xml a custom mapper

Hi, does anyone knows how to configure in pom.xml a custom BackbonePluginConfiguration instance in order to use a custom jackson mapper?

The example in [Endpoint Generator | Reference | Lit | Hilla | Vaadin Docs](https://Adding a Custom Generator Plugin) by using annotation xml in pom.xml seems not work.

I am using vaadin and vaadin-spring-boot-starter v24.4.6 with jackson-databind v2.15.4

Thank you,
Ed
