Optional. The branch of the event.
The format is like agent_1.agent_2.agent_3, where agent_1 is the parent of
agent_2, and agent_2 is the parent of agent_3.
Branch is used when multiple child agents shouldn't see their siblings'
conversation history.
public RepeatedField<string> LongRunningToolIds { get; }
Optional. Set of ids of the long running function calls.
Agent client will know from this field about which function call is long
running. Only valid for function call event.
