Question regarding agents and sessions APIs

[Minutis]

Hello,

I have a question regarding the API with Agents. I did not find a way to get an agent that is already created. Or list the agents available. Did I miss something or is the agent not supposed to be a longer lived entity (than let's say a method call)? I imagine, that you configure agents and then use them throughout your application.

Same question regarding sessions. Although I think session lifespan is shorter than agent it still would make sense to be able to get existing sessions for w/e the purpose it could be. I see that it's possible to fetch single session but I don't see a way to list all sessions.
