How to safely back up voice memos from iPhone 7 Plus to Mackbook Pro 2019

Hi, I have several hours of stories a young friend dictated on Voice Memos on my iPhone 7 Plus that I don’t dare lose! I would like to back the whole thing up on my MacBook Pro 2019. I remember reading that backing it up on iTunes might not be secure if I then delete it from my phone. It’s also in my Ipad, which is synced with my phone.

I wanted to just back up my iPhone, and the voice memos with it, onto my MacBook without using iTunes, but when I looked for the phone under the Finder menu, it didn’t show up. Only iTunes showed up, and the only option I had was whether to encrypt or not.

Does anyone know if there is a way to back up all the voice memos at one without using iTunes, with or without the rest of the content in the phone? Obviously I know very little about any of this, and I’d appreciate any advice. Thanks in advance!
