Detect if glb files children are hovered/clicked

Hi.
I am importing a glb module from Blender into ThreeJS, which consists of a bunch of children meshes and groups. I want to detect when 5 specific elements are hovered (to change their opacity), and then call an action when they are clicked.
I have been browsing the internet but with no luck. This is what I could set up from tutorials, but it just creates an white screen.

import * as THREE from 'three';

import Sizes from "./Utils/sizes.js"
import Time from "./Utils/time.js"
import Resources from "./Utils/resources.js"
import assets from "./Utils/assets.js"

import Camera from "./camera.js"
import Renderer from "./renderer.js"

import World from "./World/world.js"

export default class Experience {
  static instance
  constructor(canvas) {
    if (Experience.instance) {
      return Experience.instance
    }
    Experience.instance = this;
    this.canvas = canvas;
    this.scene = new THREE.Scene() //I set up my scene here
    this.time = new Time() //I set up time here for animations
    this.sizes = new Sizes() //I set up sizes here
    this.camera = new Camera() //I set up the camera here
    this.renderer = new Renderer() //I set up my renderer here

    this.recources = new Resources(assets) //I get the blender file from here
    this.world = new World() //I set the view here, where I load the blender file 

    this.sizes.on("resize", ()=> {
      this.resize();
    })

    this.time.on("update", ()=> {
      this.update();
    })
  }
  
  resize() {
    this.camera.resize()
    this.renderer.resize()
  }

  update() {
    this.camera.update()
    this.renderer.update()
  }
}

//Raycasting
const raycaster = new THREE.Raycaster()
const moveMouse = new THREE.Vector2()
const experience = new Experience() 

window.addEventListener('mousedown', event => {
  moveMouse.x = ( event.clientX / window.innerHeight ) * 2 - 1
  moveMouse.y = - ( event.clientY / window.innerHeight ) * 2 + 1

  raycaster.setFromCamera( moveMouse, experience.camera.perspectiveCamera)
  const found = raycaster.intersectObjects( experience.world.room.actualRoom.children )
  console.log(found)
}) //The white screen gets created from this.

Maybe there is a video or tutorial that I haven’t seen that would help me out, if you know one please let me know. I’m new to ThreeJs, so I’m still learning a lot.

I don’t know any video or tutorial, so I made you a demo. You can rotate the model. Hovered children are made reddish. For the demo, the list of hoverable children (called collectibles) contains only the children with names.
