    actionComplete: actionCompleteHandler
});
defaultRTE.appendTo('#defaultRTE');

var myCodeMirror;

function mirrorConversion(e) {
    var id = defaultRTE.getID() + 'mirror-view';
    var textArea = defaultRTE.contentModule.getEditPanel();
    var mirrorView = defaultRTE.element.querySelector('#' + id);
    var charCount = defaultRTE.element.querySelector('.e-rte-character-count');
    if (e.targetItem === 'Preview') {
        textArea.style.display = 'block';
        mirrorView.style.display = 'none';
        textArea.innerHTML = myCodeMirror.getValue();
        charCount.style.display = 'block';
    }
    else {
        if (!mirrorView) {
            mirrorView = ej.base.createElement('div', { className: 'e-content' });
            mirrorView.id = id;
            textArea.parentNode.appendChild(mirrorView);
        }
        else {
            mirrorView.innerHTML = '';
        }
        textArea.style.display = 'none';
        mirrorView.style.display = 'block';
        renderCodeMirror(mirrorView, defaultRTE.value);
        charCount.style.display = 'none';
    }
}

function renderCodeMirror(mirrorView, content) {
    myCodeMirror = CodeMirror(mirrorView, {
        value: content,
        lineNumbers: true,
        mode: 'text/html',
        lineWrapping: true,
    });
}

function actionCompleteHandler(e) {
    if (e.targetItem && (e.targetItem === 'SourceCode' || e.targetItem === 'Preview')) {
        this.sourceCodeModule.getPanel().style.display = 'none';
        mirrorConversion(e);
    }
    else {
        setTimeout(function () { defaultRTE.toolbarModule.refreshToolbarOverflow(); }, 400);

<script src="https://cdn.embedly.com/widgets/platform.js" charset="UTF-8"></script>

The above script is added to the page.

index.js
index.html
var defaultRTE = new ej.richtexteditor.RichTextEditor({
    placeholder: "Click link icon in toolbar to add the desired link",
    toolbarSettings: {
        items: ['createLink']
    },
    actionComplete: function (args) {
        if (args.requestType === 'Links') {
            if (args.elements[0].parentNode && args.elements[0].parentNode.tagName === 'A') {
                var emberEle = document.createElement('blockquote'); // to add the link
                emberEle.setAttribute('class', 'embedly-card'); // to add the class
                emberEle.appendChild(args.elements[0].parentElement);
                emberEle.appendChild(document.createElement('p'));
                args.range.insertNode(emberEle); // add the link  description to the rte content
            }
        }
    }
});
defaultRTE.appendTo('#defaultRTE');
