Playing music directly from iPhone 5s via iTunes on Mac mini

Have an old iPhone 5s (iOS 12.5.7) that is used as an iPod. Loaded with music. Mac mini (late 2012), MacOS 10.15.7.

iPhone 5s shows up in iTunes. Backed up locally to Mac mini via iTunes. Said iPhone 5s does NOT show up on desktop, ie, like an external device. Question: Is it possible to play music directly off iPhone 5s via iTunes?

Thank You for your time, James
