Automatically keep audios on Mac just like on iPhone in Monterey?

These are my settings in iOS15, and all audios automatically stay in the convo, w/o the need to manually do anything. So they do not disappear on their own, they stay, forever.

Now this instead is the only setting there is in Monterey in Messages about keeping content, be it messages or audios or photos or whatever...I suppose.

Where is the audios "expire: never" option on Mac why is it missing? Sent audios (not received) disappear on Mac almost right away unless I manually "keep" them.

If I don't remember to keep right away on Mac, or if I don't have my Mac with me, then afterwards all sent audios will be vanished...it's always been like this.

How to automatically keep sent audios on Mac w/o having to always click on that keep?!
