permit=”web-share” Attribute
An attribute is an HTML markup that modifies an HTML component ultimately.

The <iframe> is an HTML component and it may be modified with the permit=”web-share” attribute
An <iframe> permits a webpage to embed HTML, often from one other web site.

Google’s announcement makes use of this instance of the attribute in use:
<iframe permit="web-share" src="https://third-party.instance.com/iframe.html"></iframe>
Google calls this a “a probably breaking change within the Internet Share API.”

“If a sharing motion must occur in a third-party iframe, a latest spec change requires you to explicitly permit the operation.
Do that by including an permit attribute to the <iframe> tag with a price of web-share.
This tells the browser that the embedding web site permits the embedded third-party iframe to set off the share motion.”
