Hello, I succeeded developing agents with ADK, deploying them to Vertex Agent Engine, and deploy and use them in AgentSpace (a very long and not easy trip indeed!). Now I’m wondering how to handle controlled user input using forms or similiar to ask the user for specific parameters needed to the agent (example ask for a date range from/to with a calendar widget). For example, when you’re using the Gmail connector, a form with basic email sending parameters is displayed inside the AgentSpace chat. How is it possible? How to render the form by the agent? Are basic HTML forms allowed? How to process submit and send input to the underlying agent to trigger the input processing? Any real example wold be appreciated. Thank you.
