Langgraph HIL with reasoning engine API

[BalasubramanyamEvani]

Hello, I was conducting a feasibility study and was wondering if it's possible to use the Reasoning Engine API to leverage the LangGraph workflow we have with a human in the loop (using interrupts). We have a node that explicitly requests human input at a particular step in the graph.

Any example or sample to implement this would be helpful.

Thanks!
