iOS 13 will bring Apple a feature that few people expect, and that's because Americans have refused to offer it to customers. Specifically, iOS 13 should bring support for mouse connection via USB to iPad Pro, something that many customers have been waiting for these products for years.
iOS 13 will have this functionality provided through the accessibility system so it will need to be manually activated by people after purchasing their tablets. Linking your mouse with iPad Pro will take place via the USB-C port, not Bluetooth, and this restricts the types of tablet-compatible accessories via iOS 13.
The iOS 13 carries mouse support via USB to iPad Pro
iOS 13 will have this feature in full development a few months ago, and it may take several months before it is formally integrated, perhaps even after the launch of the first public release. Also, it is not clear what cursor will be visible in iOS 13 after enabling this feature, so it all depends on Apple.
If you missed last week @_connectedfm, @vitics snake and a pretty interesting scoop that he was sitting on the support of the mouse coming to the iPad as an accessibility feature. As far as I know, * it really is at work. I feel that every user will reverse this on the first day

iOS 13 will turn iPad tablets into real-time computers if they have such integrated features, but of course everything depends on what Apple wants to offer. I would not have much hopes for how IOS 13 will offer this functionality, and I recommend that you think things the same.
