I want to add a nonce to a dynamically constructed script tag. The below does NOT add any nonce to the generated script tag. Anyone an idea how the nonce can be added?

var _wss = document.createElement('script');

_wss.nonce = 'random-string';

_wss.type = 'text/javascript';

_wss.charset = 'utf-8';

_wss.async = true;

_wss.src = "url";

var __wss = document.getElementsByTagName('script')[0];

__wss.parentNode.insertBefore(_wss, __wss);

The result is:

<script type="text/javascript" charset="utf-8" async src="url"></script>

Expected result:

<script nonce="random-string" type="text/javascript" charset="utf-8" async src="url"></script>

Thanks!
