How do I make the play/pause button (F8) on my mac keyboard play/pause in the Amazon Music app How do I make the play/pause button (F8) on my mac keyboard play/pause in the Amazon Music app.

I'm running Catalina.

I have an apple wireless keyboard. https://www.apple.com/shop/product/MQ052LL/A/magic-keyboard-with-numeric-keypad-us-english-silver?fnode=56

It has media function keys (rewind, play/pause, fastforward). 

I am currently listening to music on Amazon Music. (https://www.amazon.com/b?node=16962657011)

Right now, when I press the play/pause button, it launches [Apple] Music.

How do I make it so that pressing play/pause affects Amazon Music?
This article suggests using Magic Keys to reroute media keys to third party applications.
