Where do saved audio from the iMessages app go when saved on iPhone?

When someone sends me an audio file via iMessages there's an option to "save" - Where does it go??? it's not in Files nor does it show up in the Voice Memos, like it used to.

This question was asked a couple years ago and only had one reply where they explained a workaround where you could email the files to yourself. Yes, I know you can save them to a bunch of diffrent programs on the phone (eg DropBox, OneNote, etc) but I find it hard to belive that the Save function isn't supposed to land them in the Voice Memos. Like it used to do just fine. It just seems like a dumb apple oversight.
