This is due to the fact that it is not well documented, sadly. A few console commands should do the trick if you don’t want to dig into the code deeper.
Here is a link to the documentation where it delves deeper into the topic: CommonUI Input Technical Guide for Unreal Engine | Unreal Engine 5.4 Documentation | Epic Developer Community
Furthermore, if you type into the console command search bar “CommonUI” or “CommonInput,” you can see the other options available as well.
This is not the cleanest, but this is as far as it gets currently in BP.
PS: Here is a function to move your cursor around as well. You can use the IA from Enhanced Input, so it does not have to be done in event tick.
I hope this helped!
