Shared screen has no sound.

I am a music creator. I use an M1 MacBook Pro. I want to use Zoom to share GarageBand screen for other participants to watch. However, other participants can only see the GarageBand screen I shared, and cannot hear any sound in GarageBand. I don't know how to solve this problem. I hope it can be answered here. Thank you.

GarageBand is a recording software.
