Use Fresco and screen mirror FROM iPad/Fresco TO Macbook?

Hello all, I desperately need to correct bad posture whilest working (and avoid a second spinal fusion surgery!) In trying to come up with a new, more ergonomic workflow, I need to have a screen at eye level (either my MacBook or another monitor: I'm open to suggestions but all my stuff is Mac) while drawing on my IPad Pro (with Fresco) down at lap level. It seems Sidecar is for people who want to do the OPPOSITE, that is, use Photoshop from the desktop or laptop, and use their iPad as an extra screen. I don't see how that is possible using Fresco, or is it? I don't like drawing in Photoshop: I use it to finalixe things but not the bulk of my work as an illustrator who produces hand drawn work. I'm grateful for any help!
