Are user messages stored automatically in the AI state?

[philmetzger]

I could not find anything that could help me here in the docs. But basically whenever I call my actio, are user messages automatically stored in the AI state or do I need to do that manually every time?
And if so, is this the right way to do it (before the sdk is called)

const aiState = getMutableAIState();
aiState.update((messages: ServerMessage[]) => [...messages, { role: 'user', content: input }]);
