I am building an agent with GeminiRealtime. When the user disconnects I would like to prompt the model (generate_reply) to do a tool call which summarizes the conversation and saves it to a database. I have tried

on_exit

and

ctx.add_shutdown_callback

. The issue with both is this error:

AgentSession is closing, cannot use generate_reply()

How can I hook in when the user has left, but before the model has been closed?

Thanks for reaching out, Colin. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
