any script that make my crosshair orbit the player and can be moved using joystick like mini militia

so I am making a multiplayer game but I am starting at the easiest part which is setting the players where I already did the movement and jump scripts and now I am doing the gun part where I need a script that makes my crosshair move around my character or simply orbit it and can be controlled by joystick . I've been reading things like joining two axis values and very complicated to me and I am struggling for my game anyone wanna check out my inspiration:

so I hope someone would help me I am new and trying to learn unity.

 

Joystick Vector.normalized * bounds + Player Position = crosshair position.
