Custom Imput_HTML_PDF

Hi Guys !
I have an issue with the Custom Imput, when i try add an embed PDF in HTML :

< embed src=“D:/file.pdf#toolbar=0” width=“500” height=“375” type=“application/pdf” >

The PDF is shown in the browser

but on the UIpath Custom input does not show.

Anyone know any method of VB or any solution?

Thanks !
