Any way to get back a text I deleted in Google Messages?

Check Archived first, top right menu in Messages. Swiping a conversation away archives it and it's easy to think that was a delete. If it's really gone, it's not good news. Google Messages has no bin. Your Google backup does include SMS, but you can only restore it while setting a phone up, so you'd have to factory reset the S22, and you'd lose anything newer than that backup. On a Samsung it's worth checking Settings > Accounts and backup for a Samsung Cloud backup too, see what date it's from before you decide anything.
