Langgraph Human-in-loop with librechat

[Akram12-06]

I've integrated Librechat with my custom backend built using Fastapi, Which hits an langgraph agent on every request.

In my usecase there is a HUMAN-IN-LOOP which waits for approval from user i.e., so the execution of graph will stops at a point and wait for user request.

Ones the request is recevied the agent exection starts from beginning(probably a new request).

Is there any feature in LibreChat so I can integrate with my usecase
