How can I get all the routes (from all the modules and controllers available on each module) in Nestjs?

Question

Using Nestjs I'd like to get a list of all the available routes (controller methods) with http verbs, like this:

API:
      POST   /api/v1/user
      GET    /api/v1/user
      PUT    /api/v1/user

It seems that access to express router is required, but I haven found a way to do this in Nestjs. For express there are some libraries like "express-list-routes" or "express-list-endpoints".

Thanks in advance!

main.ts

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
  const server = app.getHttpAdapter().getInstance();
  const router = server.router;

  const availableRoutes: [] = router.stack
    .map(layer => {
      if (layer.route) {
        return {
          route: {
            path: layer.route?.path,
            method: layer.route?.stack[0].method,
          },
        };
      }
    })
    .filter(item => item !== undefined);
  console.log(availableRoutes);
}
bootstrap();
