Connect my iPhone to my Mac Pro to play sound coming from my iPhone on the speakers my Mac Pro uses

Is there any way I can cause whatever audio comes from my iPhone to play on my Mac Pro. Perhaps with bluetooth? My Mac Pro showed up in the list under "MY DEVICES" when I go to Settings->Bluetooth. It wasn't under "OTHER DEVICES". I mean it was under "MY DEVICES", so at one time it seemed it was connected to my iPhone by Bluetooth. It said not connected next to it. When I tried to connect by tapping on it, I got a message saying it wasn't supported. I will by happy with any way whatsoever to play audio from my iPhone on my audio output on my Mac Pro.
