Logic Pro song added to Music on Mac but not showing on iPhone

Hi there, new Mac Mini and Logic Pro user here (but long time iPhone user). I want to add some of my new creations to my iPhone so I can play to my friends and let them laugh at me. I have worked out how to add to the Music app on the Mac, easy, but nothing is showing on the Music app on my iPhone. I don’t have a Music subscription- is that the obvious reason it won’t work ? I was hoping my own songs uploaded to Music could be done without paying for the wider subscription which I don’t want/need

Any ideas for a workaround, or other suggestions for the easiest way that other people are adding a Logic projects to be able to play on iPhone etc outside of the Logic environment.

Sorry if these are obvious questions - as I say, I’m new to both Mac and Logic !

thanks
