Currently you can't do an animation (save as video) from within the app.
But you can connect your iPad Pro to a Mac (with a ligthning cable) and use Quicktime to capture a video. This is how we create the tutorials too. Connecting the iPad Pro and Apple computer is pretty easy, takes 5 seconds.
You can save the video and share it with clients.
For Microsoft computers I recommend Airserver (https://www.airserver.com/) that does the same.
