OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 109. This policy is obsolete. The policy was a temporary workaround for non-spec-compliant enterprise applications. This policy stopped working in Microsoft Edge 107 and was obsoleted in Microsoft Edge 110. The display-capture permissions-policy gates access to getDisplayMedia(), as per this spec: https://www.w3.org/TR/screen-capture/#feature-policy-integration However, if this policy is Disabled, this requirement is not enforced, and getDisplayMedia() is allowed from contexts that would otherwise be forbidden. If you enable or don't configure this policy, sites can only call getDisplayMedia() from contexts which are allowlisted by the display-capture permissions-policy. If you disable this policy, sites can call getDisplayMedia() even from contexts which are not allowlisted by the display-capture permissions policy. Note that other restrictions may still apply.
