Is it possible to have multiple callbacks work with a single workflow?

I have a Nexus operation that starts a workflow, but this is used in multiple places. operation:

```go
var Operation = temporalnexus.NewWorkflowRunOperation(
	OperationName,
	SampleWorkflow,
	func(ctx context.Context, params Params, options nexus.StartOperationOptions) (client.StartWorkflowOptions, error) {
		return client.StartWorkflowOptions{
			ID: WorklfowID(params.ID),
			WorkflowIDReusePolicy: enums.WORKFLOW_ID_REUSE_POLICY_ALLOW_DUPLICATE_FAILED_ONLY,
		}, nil
	},
)

```

The operation works from multiple places, and there are no duplicate workflows. But only one caller gets notified after the workflow completes. Am I doing something wrong here, or is it a `NewWorkflowRunOperation` limitation or Nexus limitation?

Thank you!
