Kotlin/Java: Using ActionBuilder for the implementing Actions

Hello Team,
I am migrating my performance tests on Kotlin.
I have the following code on Scala language:

class CustomActionBuilder(name: String, func: () => Status) extends ActionBuilder {
  override def build(ctx: ScenarioContext, next: Action): Action =
    new CustomAction(name, ctx.coreComponents.statsEngine, func, next)

class CustomAction(val name: String,
                   val statsEngine: StatsEngine,
                   func: () => Status,
                   val next: Action)
  extends Action {

  override def execute(session: Session): Unit = {
    val startTime = System.currentTimeMillis

    val status = try {
    } catch {
      case _: Throwable =>

    val endTime = System.currentTimeMillis
    statsEngine.logResponse(session.scenario, List.empty, name, startTime, endTime, status, None, None)
    next ! session

By this code, I would like to have the ability to create AWS Gatling lambda and execute requests to the lambda or check the data in DB
.exec(lambda.sendStopRequest()) etc
Ps: my class is based on https://www.programcreek.com/scala/io.gatling.core.action.builder.ActionBuilder

my questions:
1 how I can implement this logic on JavaDsl, probably i should use io.gatling.javaapi.core.ActionBuilder?
2 what’s the best way to do it?
3 do you have a code example?
