How to integrate GrapesJS with Angular?

I have (followed this https://medium.com/@camiloht23/integraci%C3%B3n-de-grapesjs-con-angular-11ebf3bb80c5) installed and trying to import GrapesJS in Angular. But I am getting an error as "Could not find a declaration file for module 'node_modules/grapesjs'. 'app-test/node_modules/grapesjs/dist/grapes.min.js' implicitly has an 'any' type. Try npm install @types/grapesjs if it exists or add a new declaration (.d.ts) file containing declare module 'node_modules/grapesjs';". How to clear the error?

Step1: Install using

npm i grapesjs --save

Step2: Add Styles and scripts to angular.json

"projects": {
    // ...,
    "architect":{
        // ...,
        "options": {
            "build": {
                ...,
                "styles": [
                    ...,
                    // Add this line
                    "node_modules/grapesjs/dist/css/grapes.min.css"
                ],
                "scripts": [
                    ...,
                    // Add this line
                    "node_modules/grapesjs/dist/grapes.min.js"
                ]
            }
        }
    }
}

Step3: Refrence

Create a file name typings.d.ts in the /src/ directory if it does not exists. Open the file typings.d.ts and add the following content:

declare var grapesjs: any;

Step4: Now open your component.ts file and initialize the library:

grapesjs.init({
    container: '#gjs',
    fromElement: true,
    height: '300px',
    width: 'auto',
    storageManager: false,
    panels: { defaults: [] },
});

In your component.html

<div id="gjs"></div>

Note: Its redundant to import grapesjs in the component file.
