Click and drag camera aim

Quick background reference: I have a stationary camera in my scene that is always setup to aim at the player (not attached to it). This is also my first big step into cameras (please forgive me if this sounds kinda silly).

I’ve been trying to finish off my camera and the last thing I want to do is to add the ability for the player to click and drag on the screen to “free aim” the camera. I’ve been looking at different anwserhub posts and I either get totally lost/ can’t understand them or they work but they are meant for cameras that are attached to players or use springarms.

Do anyone know of any resources that do this or can give me some guidance with this problem?

Thank you in advance for any and all help!
