Sharing music and mic issue

Hello,

I am a yoga teacher and I like to share music when I give a course online.

Last year, I was able to share my music from spotify and have my Rodes mic plugged at the same time so my student can ear the music and my voice

Now, when I share screen with sound my mic is automatiquely desactivated

How can I give my course with music sharing and my mic at the same time 

Thanks
