Share audio and using microphone in parallel (PWA for Chromebook)

[Sunnyoga]

How can I share music while teaching my online yoga classes on Chromebook through Zoom PWA? I know it is possible to share a tab with the sound on, but in Zoom PWA this suppresses my microphone. When I then switch from sharing the tab with sound to PWA, the music stops. Is there any way to stream my camera, microphone AND sound in the same time on Chromebook PWA?
