How to access any property of a point-cloud model

I’m trying to access any property of my imported point-cloud model.
When I console.log the model within the function loader.load it works. The first problem is that I don’t know how to get the same result outside the function. I did it only with the last three lines of code but initializing the object with different name.
I used the code for point-cloud models from three.js docs and everything works fine except when I want to change the size of the points. I guess it is due to the different structure of my model (photo attached).
Here’s the code that I use.

import ‘./style.css’
import * as THREE from ‘three’

import { OrbitControls } from ‘three/examples/jsm/controls/OrbitControls.js’;
import { PCDLoader } from ‘three/examples/jsm/loaders/PCDLoader’
import { BufferAttribute, BufferGeometry } from ‘three’;

let camera, scene, renderer;

  	init();
  	render();
  	
  	function init() {

  		renderer = new THREE.WebGLRenderer( { antialias: true } );
  		renderer.setPixelRatio( window.devicePixelRatio );
  		renderer.setSize( window.innerWidth, window.innerHeight );
  		document.body.appendChild( renderer.domElement );

  		scene = new THREE.Scene();

  		camera = new THREE.PerspectiveCamera( 30, window.innerWidth / window.innerHeight, 0.01, 40 );
  		camera.position.set( 0, 0, 7 );
  		scene.add( camera );

  		const controls = new OrbitControls( camera, renderer.domElement );
  		controls.addEventListener( 'change', render ); // use if there is no animation loop
  		controls.minDistance = 0.5;
  		controls.maxDistance = 10;

  		//scene.add( new THREE.AxesHelper( 1 ) );

  		const loader = new PCDLoader();
  		loader.load( 'pointcloud.pcd', function ( points ) {

  			points.geometry.center();
  			points.geometry.rotateY( Math.PI );
  			points.geometry.rotateX( Math.PI );
  			points.geometry.rotateZ( Math.PI );
  			scene.add( points );
  			console.log(points)

  			render();
  		} );

  			window.addEventListener( 'resize', onWindowResize );

  		window.addEventListener( 'keypress', keyboard ); }

  	function onWindowResize() {

  		camera.aspect = window.innerWidth / window.innerHeight;
  		camera.updateProjectionMatrix();

  		renderer.setSize( window.innerWidth, window.innerHeight );	}
  	
  	function keyboard( ev ) {

  		const points = scene.getObjectByProperty( 'pointcloud.pcd' );

  		switch ( ev.key || String.fromCharCode( ev.keyCode || ev.charCode ) ) {

  			case '+':
  				points.material.size *= 1.2;
  				break;

  			case '-':
  				points.material.size /= 1.2;
  				break;
  		}
  		render();	}

  	function render() {
  		renderer.render( scene, camera );
  	}

// How I accessed attributes
const points2 = scene.getObjectByProperty( ‘points’ );

        console.log(points2)`
