Possible to use SideCar with MacBook Pro w/ 4 external displays?

As noted in the tech specs of the MacBook Pro (16-inch, 2019), it can support up to four external 4k monitors, and that's how I've set up mine. The maxed-out number of monitors + the laptop's display effectively give me five displays. Can I use SideCar to add an additional display to this set-up? > MacBook Pro + SideCar + **4** external displays = **6** displays Or would SideCar count as one of the 4 external displays? > MacBook Pro + SideCar + **3** external displays = **5** displays I don't currently have a compatible iPad to test this with and I can't seem to find the answer anywhere else. I also posted this question on Apple's discussion forum but as specific display-related questions seem to get few responses there, I thought I'd try here as well.
