Restore deleted imessages on Mac (MacOS Monterey 12.3.1)

I believe that Specific Feature " restore iMessages restore imessages that were deleted on the messages app on my macbook " was only introduced in macOS 13 Ventura

In this specific instance where the computer is presently running macOS 12 Monterey - what is gone is gone.

Upgrading to Ventura macOS 13 will not bring them back - sadly 😔

I'm having this same issue with Monterey 12.7.4 on an intel iMac. I have my messages backed up in time machine, but I cannot see them in my conversations when I open the Messages app from the restored backup.

Welcome and thank you too
