I am a newbie in spring boot framework and I am curious how spring-docs can detect the GroupedOpenApi. From spring-docs documentation I know that I need to have configuration like below:
`@Configuration
public class OpenApiConfig {

@Bean
public GroupedOpenApi licenseV1Api() {
    return GroupedOpenApi.builder()
            .group(v1-api")
            .pathsToMatch("/v1/**")
            .build();
}

}
`

I would like to know how sping-docs use that bean in it’s core.

I want to know how spring-docs detect and use GroupedOpenApi bean
