docs: // Enable - Enables issuing of requestPaused events. A request will be paused until client calls one of failRequest, fulfillRequest or continueRequest/continueWithAuth.
  // patterns - If specified, only requests matching any of these patterns will produce fetchRequested event and will be paused until clients response. If not set, all requests will be affected.
  // handleAuthRequests - If true, authRequired events will be issued and requests will be paused expecting a call to continueWithAuth.
