I'd guess you already know the answer to this question, since iPadOS 13 has been out for a while. The answer is "Yes, but..." For the benefit of iPad users who don't have one, but are considering a ProPoint or GT mouse: 1) Through the accessibility settings (Settings > Accessibility > Touch > AssistiveTouch), there is limited mouse pointer support for general iPad use. It won't turn your iPad into a Macbook, but with your mouse you can mimic touch operations: launch apps, go to the home screen, tap buttons, etc. It's not a precision pointer in this mode. It's essentially a virtual finger. 2) With some remote access apps, like Jump Desktop and the beta version of Microsoft's Remote Desktop client, you can use it as a regular mouse when you're connected to a PC. Here it does act like any other mouse.
