var runtimeStatus = new List<OrchestrationRuntimeStatus>
{
  OrchestrationRuntimeStatus.Running
};
var source = new CancellationTokenSource();
var token = source.Token;
var statuses = await starter.ListInstancesAsync(new OrchestrationStatusQueryCondition()
{
 RuntimeStatus = runtimeStatus
}, new CancellationToken());

This code is not compatible with isolated worker. How do I change it?
