Save unsubmitted Draw tool tasks annotations when closing Figma Make

I would like to request that drawings made with the Draw tool in Figma Make are automatically saved, even when the user closes the window before submitting the prompt.
Currently, if a user runs out of AI credits and cannot send the prompt, all drawings and annotations are lost when the window is closed.
It would be very helpful if the Draw tool's markup could persist in the file or chat history, so users can return and submit their prompt once their AI credits are replenished. This would prevent the loss of significant work and improve the user experience.
