Disable Autoplay of Music in Apple Music on Macbook Air with Bluetooth Headphone Connected

With my BT headphones that are multipoint connected to my Macbook Air & my phone, no music is being played, and Apple Music isn't even open or running, when I receive a phone call and then hang up, Apple Music will start and begin playing a song. I have tried what is suggested here Disable autoplay of Studio Buds from Mac - Apple Community but I do not have the Autoplay that is mentioned. Is there another setting that will allow me to turn this off? I primarily use the headphones for VoIP calls on the Mac, not listening to music.
