Have iphone 14 pro max and new PC. Want to transfer music from phone to PC so I can use itunes again to add new music.

I can't find a way to transfer the music I have on my phone to my new PC, without paying money for an app or sync library which I don't feel I should have to. They're there on my phone. They've been there ever since my iphone 7, but I had the same PC for many years and it was never a problem. All of the music was on that old PC's drive. This new PC doesn't have any of the music I added to my phone all those years ago.

Is there no way to do it with itunes?

I've searched and googled this issue. I see a lot of outdated methods that don't work and suggestions for apps that are rather expensive. All I want to do is have itunes on my new PC recognize the music I already have on my iphone and be able to add new music without a "sync" deleting what I have, which is what will happen if I can't get this music off my phone and onto my PC. It needs to be there on my drive first.
