New Input System 2019 and UI

I have integrated the new Unity Input system, using this Video https://www.youtube.com/watch?v=Gz0YcjXBJ3U. As I wanted to implement UI I did not manage to get the buttons to be interactible. I have the feeling that the new input system is not set up properly to work with the Unity UI. As I inspected the EventSystem GameObject, It displayed a warning that it is not set up to work with the new Input System and prompted me to fix it. I clicked on that and a new component was added with the InputActionsAsset assigned. This is what the Error looked like. It did not work after that still. And adding the UI part of the created default Input Asset to my other InputActionAsset, which already works in game did not do the trick as well. Now it looks like this I would heavily appreciate any help on this topic.
