Generate ascii documentation from openapi 3.0 with samples

I'm using quarkus and openapi-generator-maven-plugin to generate ascii documentation from openapi 3.0 yaml file, but I'm not being able to add the example sample code to request/response. I have the mustache template but I'm not being able to generate or understand how to automatically create the http-request.adoc/http-response.adoc for all api request.

My directory hierarchy

scr  
 └── asciidoc
         └── templates  
               └── index.mustache

In my pom I have

                </configOptions>
            </configuration>
        </execution>
    </executions>
</plugin>

In the index.mustache I have (copied from openapi-generator index.mustache)
