Motorola G8 Plus running Android 9 - not restoring sms messages from Google backup

Just done a factory reset only to have the carrier Motorola inform that the Google messages app will not restore my messages.

What are my options here? highly important I retrieve these messages to prove that someone scammed me. Please make suggestions around software, debugging options, or an android model that will recover these messages.
