Try serverless-workflow-timeouts-showcase-embedded, start service using quarkus:dev

Try to access http://localhost:8080/q/swagger-ui/

Log shows:

ERROR [org.kie.kogito.jobs.service.resource.error.NotFoundExceptionMapper:59] (executor-thread-0) Handling HTTP Error RESTEASY003210: Could not find resource for full path: http://localhost:8080/q/swagger-ui/ 

Then, if you comment out dependency kogito-addons-quarkus-jobs-service-embedded, Swagger Ui works fine.
