Importing an own Dolby Atmos mix in the Apple Music App not possible?

Hello,

I have made my first own (test) Dolby Atmos mix with Apple Logic using ADM BWF (like described in the Logic manual). The mixdown file has the extension WAV.

I wanted to listen to it with my iPhone and my Mac and tried to import the file in my local Apple Music app. The app does not import that file. There is not error message when I select the file, but is not inside my local app.

How can I listen my own Dolby Atmos mix using Apple Music on my Mac (with headphones)???

Any hint?

Thank you.
