Permissions-Policy: web-share

The HTTP Permissions-Policy header web-share directive controls whether the current document is allowed to use the Navigator.share() method of the Web Share API to share text, links, images, and other content to arbitrary destinations of the user's choice.

Specifically, where a defined policy blocks usage of this feature, Navigator.share() calls will return a Promise that rejects with a DOMException of type NotAllowedError.
