Mouse Delta not working

Hi, i’m new to Unity and trying to get a character controller up and running.

I’m using the new Input System (with Unity events) and Cinemachine for the camera. Now i have the problem, that i have no idea how to use the mouse delta correctly. At first i added the InputProvider component to my FreeLookCamera that follows the player around. Then i made an input with action type: value and the delta [mouse] binding. Then i plugged that input to the InputProvider and I expected it to work right away, but nothing happens at all.

Then i tried to create a method in my character controller script, that should be invoked when the mouse delta is changed, and added a Debug.Log() to see what is going on. But nothing is showing either. Only when i change the input type to something like button and a key on the keyboard, the method is called.

I also looked around online, and it seems like this should work. So i have no idea what i’m doing wrong. Help would be very much appreciated!

Ok, i tried around a bit more and it seems that the mouse buttons are not working either. Do you have to enable the mouse first or could there be something else i missed?
