How to share audio without having to share your screen?

I couldn't find a way to share only audio/music files you play on PC while another person is already sharing their screen.

The only thing I could come up with is everybody joining 2 meetings simultaneously. First one where the coach is sharing. And the second one stays in the background and everybody is muted. Only when needed people would unmute themselves in the second meeting to share audio.

Or just share the audio files with the coach, so the coach plays them :?

If nobody else has a solution for this, you could give an example of what you are trying to play and how many people you expect to want to share their audio like this, so that we can figure out the best workaround for you?

Thanks for the response @ryan-gosling !

To clarify, it's just one coach that is trying to share their audio. I've attached a screenshot to better show what the issue is:
