Streaming messages vanish as final messages are sent from react agent on langraph server

[vivek100]

I am using langraph react sdk on frontend and langraph server to run a react agent.

The intermediate tool messages are streamed and are rendered as new messages the message array goes to size 50 and then the final response is sent the backend sends new message array with 12 messages.

On frontend what happens is user sees bunch of Ai responses and they just vanish when the React agent is done.

Now i understand why these messages are removed they help manage context size. I agree. But can i identify them somehow on frontend and not render them as messages but as thinking state?

I tried 4-5 approaches, there are complex ways to do this but seems overkill. Maybe there is a better way.
