How can I make a 2D top-down camera follow my player AND the mouse a bit

Hello everyone! I am currently working on a 2D top-down game and I have a little problem:

I want the camera to always stay with the player but I also want to be able to look around with my mouse but not far so the player is always in sight. So far I have set up a Cinemachine 2D Camera that follows my player but I dont know what to do so it also considers the mouse position. Can somebody help me? Thanks
