Is there a way to see my edit history?

I accidentally deleted some text. Normally I can use ctrl+z to undo and ctrl+y to redo, but it didn’t allow me to continue undoing to the part that I deleted/needed. Is there any way for me to retrieve what I lost? Thank you!

I saw this article ([https://help.kamiapp.com/en/articles/647904-how-are-my-files-and-annotations-stored]) but when I looked at my ‘view all’ section, no copies showed up.
