Where can I find the notebook which has been not saved ever if I accidentally shut down the livebook server?

I accidentally shut down the livebook server and the code I’ve written get lost. How can I get it back?

Thank for any reply!

I think if you’ve never saved it, then it’s gone (it was ephemeral and stored in memory). If you have saved it once then I think Livebook will continue to save when you make changes.
