THREE.Group.apply(this);

[HJ959]

Hello again

So I can import three-steer using this repo https://github.com/AlexusBlack/three-steer I've taken the main file with the Entity and SteeringEntity classes and saved in my src.

With some tweaks, I needed to add
import * as THREE from 'three';
To the beginning of the file and change
module.exports = { Entity, SteeringEntity };
to
export { Entity, SteeringEntity };
Then I can import in my main.js using
import { SteeringEntity } from './three-steer';

Now I can import it fine, but when I go to implement using
let entity = new SteeringEntity(mesh); scene.add(entity);

I get the following error
three-steer.js:11 Uncaught (in promise) TypeError: Class constructor Group cannot be invoked without 'new'

The line causing the issue is (in Entity class)
THREE.Group.apply(this);

Couldn't find any docs for THREE.Group.apply, is it outdated code? What's the purpose of it?
Would love to update it, I tried this but got another error

const group = new THREE.Group(); group.add(this);
Error
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'remove')
