How do I retrieve lost notes on my iPhone and iCloud?

I read ALL of the articles on this ridiculous problem with Apple. My notes mysteriously disappeared not only from my iPhone 16 pro, but also from my iCloud account. So, the safety net of having a backup was a complete facade. I chatted and called with Apple support and they could do NOTHING. "Sorry, sir, your notes are gone forever..." is basically the conclusion they gave me.
