How to play Dolby Atmos on Mac OS application

I'm using the MacBook Pro (2020 series).

The above page says that Dolby Atmos is supported for built-in speakers, but I don't know how to play.
I can't found the settings for playing with Dolby Atmos on MacBook Pro, so how can I play with Dolby Atmos in Mac OS application written by mysellf ?

Execution environment:
MacBook Pro (2020) Big Sur 11.5.2
CPU: Apple M1
Xcode: 12.5.1
