How save value to state from an agent?

[KokoDoko]

I created an Agent in Flowise Cloud. The agent uses tools and a document store.

I want to keep track of a users "progress" in the conversation (a number that increases) using a STATE variable. The state is set to 0 in the start node, and it persists. BUT I cannot find how to update the STATE once the agent is running?

Many nodes, including the LLM node, have an option to "update state", but not the agent node. For the LLM node you can use JSON structured output and then save each field in its own state variable. I tried connecting an extra LLM to the agent but that has its own problems.
