If I'm Using iCloud Messages, Do I Have Any Time to Recover Accidentally Deleted Texts?

Apparently, there is incredibly little documentation for iCloud Messages. When I search anything relating to recovering messages, even if I include iCloud in the search, I just get the usual methods, which presuppose local storage/backups, so those won't work for me. I understand that if I use iCloud Messages, deletions will immediately sync across devices, but is there really no way to undo that, even within a day or two? I absolutely need to recover these texts, and it seems ridiculous that a stupid mistake with the palm of my hand would permanently erase years of messages with at least a dozen contacts with no way of undoing it.

I am incredibly appreciative of any help and information. Definitely turning off iCloud Messages after this.

Note: I don't have the newest iOS, so I can't use that "recently deleted" tab.
