Help with focus feature

Hi i am making a combat game and i need some help, i want to add a feature which lets the player focus on a part/another player, like the camera is facing another part, while the player is still in the frame, how do i do this?

(it basically focuses between two objects)

I assume you’re referring to a feature similar to holding ZR (default layout) on the Nintendo Switch in The Legend of Zelda: Breath of the Wild?

Idk breath of the wild, im reffering to the game alternate battlegrounds
