Mac) How can i mute music(or any kinds of audio) when I receive phone call on mac?

when I receive phone call on mac (through facetime), music does not automatically stop.

This is annoying when I use airpods because audio quality gets really bad and its volume becomes louder than setting. that even makes people near me able to hear the music playing on my airpods max.

so How can I stop music automatically when receiving phone call??
