Adjust the field of view of the camera in ThreeJS

I'm currently working on adjusting the field of vision for a camera without having to create a new one. So far, I've successfully achieved this for the position using the following code:

camera.position.set()

camera.fov.set()

Unfortunately, this approach is not functioning as expected in my script. Does anyone have any alternative solutions that could be quickly implemented?

camera.fov = 20;
camera.updateProjectionMatrix();

There are plans to refine this process in upcoming developments...
