How can I deep fusion babylonjs and cesium?

Questions
1

I watched GitHub - Hypnosss/cesium-babylonjs this project,but it is just do some thing with camera synchronization，and it is dependence with two different dom. that I can not manipulation babylonjs meshes or any events. Is there any way or idea to deep mix this?I am very much looking forward to and grateful to someone who can answer this question！

Would you expand on that, and I’d like to ask you exactly how to do it

import * as BABYLON from '@babylonjs/core/Legacy/legacy'
import { load, registerLoaders } from '@loaders.gl/core';
import { Tiles3DLoader, CesiumIonLoader } from '@loaders.gl/3d-tiles';
import { Tileset3D } from '@loaders.gl/tiles';

class Core {
    canvas
    num = 0
    constructor(canvas, option) {
        this.canvas = canvas
    }


    async init() {

        const engine = new BABYLON.Engine(this.canvas);
        this.engine = engine
        let scene = new BABYLON.Scene(engine);
        this.scene = scene


        scene.createDefaultCameraOrLight(true, true, true);
        scene.lights[0].intensity = 1
        scene.lights[0].diffuse = new BABYLON.Color3(0.9, 0.9, 0.7)

        window.addEventListener("click", (e) => {
            console.log(e)
            var pickResult = scene.pick(e.x, e.y);
            if (pickResult.hit) {
                // pickResult.pickedMesh.material.zOffset-=-1
                console.log(pickResult)
                // pickResult.pickedSprite.angle += 0.5;
            }
        })




        let defaultCamera = scene.getCameraByName("default camera")
        defaultCamera.mapPanning = true

        this.loadModel()
        console.log(scene)

                                await this.loadGltf(t.gltf)

                    }
                    if (Array.isArray(item?.children)) {

        }

        loaderTiles(tileset3d.root.children)

            const file = new File([gltf.buffers[0].arrayBuffer], "file.glb");
            await BABYLON.SceneLoader.AppendAsync("file:", file, this.scene, (e) => { }, ".glb")
            this.engine.hideLoadingUI()
        } catch (error) {

Thank you very much. I’ll try it first
