How to paste a SVG image to Word from Web (the Async Clipboard API)?

• I try it like this:

const clipboardData = {};
const blobSvg = new Blob([svgText], {type:'image/svg+xml'}
try {
    console.log(clipboardData)
	await navigator.clipboard.write([
        new ClipboardItem(clipboardData),
	]);
} catch (err:any) {
	console.error(err.name, err.message);
}

Word did not accept it. Something wrong with encoding type content ofimage/svg+xml

---

Other info:

• I insert svg in Word properly, then copy it, and inspect the content of image/svg+xml ,which is binary data.(with the help of web online tool)
• So, i wonder which encoding algorithm was used to image/svg+xml in Office?

How many html elements are supported by microsoft_365？

Currently, i know that element for div,table... is supported paste to office and preserve style , by set text/html in ClipboardItem

Is there a official list for html element supported paste in office?
