Parsing Cucumber Feature Files into JSON or NDJSON using Java with Cucumber 7.6.0 or Gherkin-Java 24.0.0 - automation

Question

Background of the Question:
Earlier Issue:
I have already asked this question in the past with attached thread below but the use case was different in that case. I just needed a way to print the JSON into stdout using (NodeJS) cucumber-js. I used Native Cucumber parsing using cucumber CLI commands as per (https://github.com/cucumber/cucumber-js/blob/main/docs/formatters.md).
How to convert cucumber gherkin feature files into JSON or AST format?
Current Issue:
I want to Parse Gherkin Feature Files to JSON using Java. These JSON files would be later interpreted and rendered into a front end dashboard where we could filter feature files based on tags, scenarios and text match for features.
I came through React cucumber (https://github.com/cucumber/react-components) Library but this is more of a JS Based solution and I need to process the Parsed Feature file JSON before passing to the view layer.
Can someone please provide the code snippet for parsing Gherkin Feature file to JSON in Java. I went through below threads but all are using deprecated code.

You can use io.cucumber.junit.Cucumber for reference. Briefly in your case you would do the following:
public class Main {
public static void main(String[] args){
RuntimeOptions runtimeOptions = new CucumberPropertiesParser()
.parse(CucumberProperties.fromSystemProperties())
.addDefaultFeaturePathIfAbsent()
.build();
SynchronizedEventBus bus = synchronize(new TimeServiceEventBus(Clock.systemUTC(), UUID::randomUUID));
FeatureParser parser = new FeatureParser(bus::generateId);
Supplier<ClassLoader> classLoader = ClassLoaders::getDefaultClassLoader;
FeaturePathFeatureSupplier featureSupplier = new FeaturePathFeatureSupplier(classLoader, runtimeOptions,
parser);
List<Feature> features = featureSupplier.get();
ObjectMapper objectMapper = new ObjectMapper();
System.out.println(objectMapper.writeWithDefaultPrettyPrinter().writeValueAsString(features));
}
}
