For security reasons, the getDisplayMedia() web API requires a prior user gesture ("transient activation") to be called or the API will fail. When this policy is configured, admins can specify origins on which this API can be called without prior user gesture. For detailed information on valid url patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. Note: * is not an accepted value for this policy. If this policy is not configured, all origins require a prior user gesture to call this API. Example value: https://www.example.com [*.]example.edu
