Is There More Efficient Way to Toggle Dolby Atmos/Stereo Menu in Apple Music?

I often flip between Dolby Atmos & general stereo audio.

This is the macro I've created with keyboard Maestro and AppleScript:

It works well but as you can notice, it's not intuitive. I think there must be a simpler method to do it,
but I don't know how to figure out the element name or operators in AS.

Can someone help me figure it out?

I’m a novice with AppleScript but the Music app has very poor integration with it. Without being at a computer and able to look at the AppleScript dictionary for the Music app, I imagine your solution is probably one of the best, if not only solutions.
