Share sound on an Android tablet

[Iboya]

I'm a fitness instructor and I use zoom for my online classes. I just bought a tablet (android) with the intention to have a smaller device that I can carry easily werever I go and be able to keep my classes from it. I installed zoom but when I'm in a meeting I don't have the same options as on a laptop. Sound share is missing, and that is crucial to share the music I'm playing with the participants. I can share the screen and then the audio sound but then the video is not working. Can I do anything to fix this or zoom doesn't t support these features on a tablet. I checked zoom on my phone and it's the same, no sound share option. I just want to know if I should go back to my laptop or there are things to do to have this option. Any help is much appreciated.
