Extensions that connect to one of these origins will keep running as long as the port is connected. If unset, the policy's default values are used. These are the app origins that offer SDKs that are known to not offer the possibility to restart a closed connection to a previous state: - Smart Card Connector - Citrix Receiver (stable, beta, back-up) - VMware Horizon (stable, beta) If set, the default value list is extended with the newly configured values. The defaults and policy-provided entries will grant the exception to the connecting extensions, as long as the port is connected. Example value: chrome-extension://abcdefghijklmnopabcdefghijklmnop/ chrome-extension://bcdefghijklmnopabcdefghijklmnopa/
