Core.js:6456 ERROR TypeError: quill.getModule is not a function

I have the following component and i am getting the issue ERROR TypeError: quill.getModule is not a function

import { AfterViewInit, Component, ViewChild } from '@angular/core';
import Quill from 'quill';
import QuillCursors from "quill-cursors";

import * as Y from 'yjs'
import { QuillBinding } from 'y-quill'

var document: any;

selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.sass']

export class AppComponent implements AfterViewInit {

quill: any;
ydoc: any;
ytext: any;
binding: any;

@ViewChild("editor",{static: false}) editor: any;

ngAfterViewInit() {

    Quill.register('modules/cursors', QuillCursors);
    this.quill = new Quill(this.editor.nativeElement, {
    modules: {
        cursors: true,
        toolbar: [
        // adding some basic Quill content features
        [{ header: [1, 2, false] }],
        ['bold', 'italic', 'underline'],
        ['image', 'code-block']
        history: {
        // Local undo shouldn't undo changes
        // from remote users
        userOnly: true
    placeholder: 'Start collaborating...',
    theme: 'snow' // 'bubble' is also great

    // A Yjs document holds the shared data
    this.ydoc = new Y.Doc();

    // Define a shared text type on the document
    this.ytext = this.ydoc.getText('quill');

    // Create an editor-binding which
    // "binds" the quill editor to a Y.Text type. 
    this.binding = new QuillBinding(this.quill, this.ytext);

i tried printing the quill object and there isn’t a method named getModule

any help would be great
