How to rotate an object with the mouse?

Question

Unity

Hello! I have such a problem that I have a beam and I need to be able to rotate it along the Z (Left / Right) axis when holding the left mouse button. But for how much my programming level is the most basic, I hope you can help me. I have a 2D game.
Please do not say that you can use this or that, as I will not understand anything. I would be very grateful for the links to the video tutorials.

There are such things as Input and GetAxis. Here you need to learn with them) There are many videos on the Internet, choose which one suits you) You can build on this:

void FixedUpdate(){
if(Input.GetKey(KeyCode.Mouse0)) //если зажата ЛКМ
{
obj.transform.rotate(0f,0f, Input.GetAxis("Mouse X")); //обьект вращаеться по z относительно перемещения мышки по вектору x
}
}

ps do not be lazy to google, everything will always not be decided for you.
