-- `options: {SubscriptionOptions}`
+#### `request(options) => Observable<ExecutionResult>`: returns observable to execute the operation.

   * `context: Object` : use to override context for a specific call
-- `handler: (errors: Error[], result?: any) => void` : function to handle any errors and results from the subscription response

-#### `unsubscribe(id) => void` - unsubscribes from a specific subscription
-- `id: string` : the subscription ID of the subscription to unsubscribe from
