A note disappeared and never showed up

I wrote a note using the Notes app today on my iPhone 15Pro and swiped away from the app.

Just now I logged on to my MacBook and opened Notes to start working on the document. However, the note I wrote earlier was nowhere to be seen.

I took up my iPhone, opened the Notes app and it was open in the app. I clicked the "All iCloud" button to go back and see if the Note just hadn't synced.

However, that's when the Note fully disappeared from my phone as well. It's not in the Recently deleted folder (did not even have the folder before I tested to delete a note I didn't need anymore), it cannot be found using the search, nor anywhere on iCloud.com, on my phone, or on my Mac.

How to recover the note I wrote that has urgent information?
