1. Is this request related to a challenge you're experiencing? Tell me about your story.

When I customize tools, they can only return data using return, and the data can only be returned after the tool has completely finished. However, I have some tools that take a long time and return data in a streamed fashion, meaning they return some data after each process completes. How can I send the streamed return values from the tool to the front end? Can this be achieved using something like queuemanager.publish()? Is there a related demo I can refer to?
