CKEDITOR5 - Angular8: TypeError: this.editor.create не является функцией

Я пытаюсь интегрировать CKEDITOR 5 в свой проект Angular 8. Я создал собственную супер-сборку с дополнительными плагинами и с ClassicEditor и InlineEditor (используя это руководство: https://ckeditor.com/docs/ckeditor5/latest/builds/guides/integration/advanced-setup.html#create-super-builds) .

Я импортировал CKEditorModule в свой общий файл модуля. Ниже мой файл компонента:

import { Component, OnInit } from '@angular/core';
import * as CKEDITOR from '@ckeditor/ckeditor5-build-classic';

@Component({
    templateUrl: './cke5.html',
    styleUrls: ['./cke5.scss'],
    selector: 'app-cke5'
})
export class CKE5  {

    loader: any;

    public CEditor = CKEDITOR.ClassicEditor.create( document.querySelector( '#editor' ), {
        extraPlugins: [ this.imageUploadAdapterPlugin ],
    } )
    .catch( error => {
        console.log( error );
    } );

    constructor() {
        console.log(CKEDITOR.ClassicEditor);
    }

    uploadImage() {
        return this.loader.file
            .then( file => new Promise( ( resolve, reject ) => {
                console.log('UPloading..');
            } ) );
    }

    abortImageUpload() {
        console.log('Abort image upload.')
    }

    imageUploadAdapter(loader: any) {
        this.loader = loader;

        const uploadInterface = {
            upload: this.uploadImage,
            abort: this.abortImageUpload
        };

        return uploadInterface;
    }

    imageUploadAdapterPlugin( editor ) {
        editor.plugins.get( 'FileRepository' ).createUploadAdapter = ( loader ) => {
            return this.imageUploadAdapter(loader);
        };
    }
}

Я получаю сообщение об ошибке TypeError: this.editor.create is not a function:

Однако, если я просто назначу CKEDITOR.ClassicEditor без вызова create в приведенном выше коде, он будет работать нормально, редактор загружается и работает нормально.

public CEditor = CKEDITOR.ClassicEditor;

Что я здесь делаю не так? Любая помощь приветствуется.

ИЗМЕНИТЬ

Пройдя через документы, я обнаружил свою ошибку. С изменениями ниже я смог заставить его работать.

import { Component, OnInit } from '@angular/core';
import CKEDITOR from '@ckeditor/ckeditor5-build-classic';

@Component({
    templateUrl: './cke5.html',
    styleUrls: ['./cke5.scss'],
    selector: 'app-cke5'
})
export class CKE5  {
    public CEditor = CKEDITOR.ClassicEditor;
    loader: any;

    public editorConfig = {
        extraPlugins: [  ]
    };

    constructor() {
    }

    public onReady( editor ) {

        editor.plugins.get( 'FileRepository' ).createUploadAdapter = ( loader ) => {
            // Configure the URL to the upload script in your back-end here!
            return this.imageUploadAdapter(loader);
        };
    }

    imageUploadAdapter(loader: any) {
        this.loader = loader;

        const uploadInterface = {
            upload: () => { return this.uploadImage(this); },
            abort: () => { return this.abortImageUpload(this); }
        };

        return uploadInterface;
    }

    uploadImage(that: any) {
        return that.loader.file
            .then( file => new Promise( ( resolve, reject ) => {
                console.log('UPloading..');
            } ) );
    }

    abortImageUpload(that: any) {
        console.log('Abort image upload.')
    }
}

И в шаблоне:

<ckeditor [editor]="CEditor" (ready)="onReady($event)" [config]="editorConfig" data="<p>Hello, world!</p>"></ckeditor>
