Permissions-Policy: display-capture

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTTP Permissions-Policy header display-capture directive controls whether or not the document is permitted to use Screen Capture API, that is, getDisplayMedia() to capture the screen's contents.

If display-capture is disabled in a document, the document will not be able to initiate screen capture via getDisplayMedia() and will throw a NotAllowedError exception.
