How can I set camera auto rotate with 3rd person character?

Hi, I attached the camera to the 3rd person character, so the camera is following the character wherever it moves. But the angle of the camera is fixed. I want to set the camera that always follows behind the character. In other words, when the character turns left or turns right, the camera would always auto rotate to the character’s back and only constraint to the back of the character.
What can I do to achieve this?
Thank you!

try to enable use Controller Rotation Yaw in the Character Class Defaults, though it depends a bit on how you handle your controls and stuff, if that doesnt help Screenshots of your Blueprint Setup of the Camera and controls would be helpful.
