How to save voice assistant responses?

I have ChatGPT set up through the OpenAI integration, and I have Home Assistant assist set up as well. Both work fine. How can I store the responses? I want to display the text on my dashboard. There doesn’t appear to be any attributes from the conversation entities that would be helpful. I know about input_text, but I don’t know how to pass the data to it (plus the character limit is only 255, which isn’t ideal).

I’m interested in something very similar.
I want to enable chatgpt on multiple voice assistants in the house so that also the kids could start using it.

Mainly because of the kids, I want the following :
To have a log in a dedicated file with :
Time ; Device_name : question_asked : answer_received

Is this doable?
