Is there any way to recover overwritten notes on mac?

I pasted something on top of a note on my Mac that had some moderately important stuff, switched notes (which means no ctrl-z), and I'm trying to recover it. My first mistake is that I unfortunately don't have a backup that includes it (iCloud or Time Machine.) So far I've: - tracked down the NoteStore.sqlite (-wal, -shm) which, as far as I can tell from googling, acts as a change log for all your notes along with the -wal which stores overflow - managed to extract the data stored in blobs from ZICNOTEDATA (

hex(zdata) from ZICNOTEDATA

) - realized each row is the raw version of a .gz (starts with 1F8B0800000...) And this is where I'm stuck now, probably because I don't have the right vocabulary to google it. Ideally, I want to put each row of this sqlite column into a "real" gzip in a folder somewhere, unzip them all into .txt files, and view as the original note. If not, I can go one-by-one and unzip them until I find the one I need. Also, I'd like to avoid any external software. Any ideas or easier ways to do this? Thanks!
