<div id="editor"></div>- In JavaScript and within a
<script>tag placed before the closing tag</body>, create the editor using theregisterfunction, your editor html element and a simple configuration:
const editorElement = document.getElementById('editor');
iink.register(editorElement, {

applicationKey: '#YOUR MYSCRIPT DEVELOPER APPLICATION KEY#',
hmacKey: '#YOUR MYSCRIPT DEVELOPER HMAC KEY#'
