How to add a camera offset to a collision sphere


I am using the 3rd person template and I created a box with a collision sphere around.
It triggers some overlay text and graphics in a widget.

I would like to add a dynamic camera offset - camera sliding slightly to the right so the character is not centered anymore but more on the left, and there is room on the screen right part to display the graphics. Then camera should dynamically revert back to normal position when the character leaves the collision sphere.

Any idea how to do that ? important is that the camera always moves to the right, no matter from which side the character enters the sphere. So no static world space position or fixed invisible target to look at, only a slight offset to the right.

Thank you very much for you help
