Is it possible to replace Wacom with iPad using Astropad?


New to Astropad - working on an iMac late 2015 & 2018 iPad Pro 11" I can see the usability in having full version of photoshop on my iPad but I want to know is there a way I can use my iPad/Pencil to replace my Wacom (M Intuos Pro) so I can be looking at my iMac screen and using the iPad as a tablet? At the moment the iMac’s cursor does not move with my iPad pencil movement, only after I have clicked on something.
