Software\Policies\Microsoft\Edge\WindowManagementBlockedForUrls Description
Lets you configure a list of site URL patterns that specify sites which can automatically deny the window management permission. This limits the ability of sites to see information about the device's screens. This information can be used to open and place windows or request fullscreen on specific screens. For detailed information on valid site URL patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. Wildcards, *, are allowed. This policy only matches based on site origin, so any path in the URL pattern is ignored. If this policy isn't configured for a site, then the policy from 'DefaultWindowManagementSetting' (Default Window Management permission setting) applies to the site, if configured. Otherwise the permission follows the browser's defaults and lets users choose this permission per site. Example value: https://www.example.com [*.]example.edu
