Getting all the invoked nodes after excuting workflow in Langgraph

[AMMISAIDFaical]

I compiled a workflow and i am trying to pass a list of questions for my worflow and for each question save all the triggred agents in my graph. in order. Is there any paramater returns all the invoked nodes ?

workflow = StateGraph(AgentState)

workflow.add_node("agent_a", agent_a_node)
workflow.add_node("agent_b", agent_b_node)
workflow.add_node("agent_c", agent_c_node)
workflow.add_node("agent_e", agent_d_node)
workflow.add_node("agent_f", agent_e_node) 
workflow.add_node("agent_g", agent_g_node)
workflow.add_node("call_tool", tool_node)

workflow.add_edge(START, "agent_a")

workflow.add_conditional_edges(
    "agent_a",
    user_question_routing,
    conditional_members
)

workflow.add_conditional_edges(
    "agent_b",
    sub_agents_router,
    {
        "agent_f": "agent_f", 
        "call_tool": "call_tool", 
        "agent_c": "agent_c", 
        "agent_e": "agent_e",
    },
)

workflow.add_conditional_edges(
    "agent_c",
    worker_router,
    {
        "agent_f": "agent_f", 
        "call_tool": "call_tool", 
        "agent_e": "agent_e", 
        "agent_b": "agent_b",
    },
)

workflow.add_conditional_edges(
    "agent_e",
    worker_router,
    {
        "agent_f": "agent_f", 
        "call_tool": "call_tool", 
        "agent_b": "agent_b", 
        "agent_c": "agent_c",

    },
)

#tool node
workflow.add_conditional_edges(
    "call_tool",
    lambda x: x["sender"],
    {
        "agent_c": "agent_c",
        "agent_e": "agent_e",
        "agent_b": "agent_b"
    },
)

workflow.add_edge("agent_f", "agent_g")
workflow.add_edge("agent_g", END)

I need something like this :

events = graph.stream(
        {
            "messages": [user_input],
            "max_iteration": 6,
            "num_iteration": 0    
        },
        thread,
        stream_mode = "values"
    )
    
    for event in events:
        print(event)
        print()

    state_snapshot = graph.get_state(thread)
    state = state_snapshot.values
    
    print(state.get_all_triggered_agents) ### ===> [agent_a, agent_b..]
