How to return client IP address in loopback 4

Question

I want to return either IPv4/IPv6 IP in the loopback4 application? How do I modify the below code to get IP address?

import {get, param} from '@loopback/rest';

    export class GreetController {       
      @get('/', {
        responses: {
          '200': {
            description: 'greeting text',
            content: {
              'application/json': {
                schema: {type: 'string'},
              },
            },
          },
        },
      })
      greet(@param.query.string('name') name: string) {
        return `hello ${name}`;
      }
    }

You should also add this code in server.js to grant the real ip, otherwise you´re getting the load balancer IP:

app.set('trust proxy', ['loopback', 'linklocal', 'uniquelocal']);
