volum control

Hi!

I would like to have control on how loud I listen each app running on the ipad pro at the same time. Is there a setting or an app that allow this control? I usually put a yoga app and a youtube/spotify music on top. However I can berly listen the music, because it gets automatically lowered down. Is there a possibility to take control about thit in any way?

Thank you,

Best regards,

Emma
