assign apps to a desktop in Mission Control
Mission Control allows you to assign an app to particular desktop, so you can keep your work organised in different screens, and move between tasks with a swipe of the trackpad.
The easiest way to assign an app to a desktop is to first run the app so it appears in the Dock. Then, if you’re not already in the desired desktop, change to the desktop that you want the app to always appear in.
Next, place the cursor over the icon, and right-click (or two-finger tap if you have this gesture set for the trackpad).
Navigate through options and assign the app to ‘This Desktop’. That’s it!
