How to rotate an object so that its top part points to another object?

Answer 1

Alternatively, use the LookAt method from Unity. But, it will allow you to look at the face of the object, where the face is on the X axis. This is corrected as follows ...
We use the main (parent) object as a shell, we put the object we need in it, which becomes a child. We put the parent object in the inspector in _listener. Since the method provides the ability to look along the X-Axis, we turn the child object to the desired angle so that its top is along the X-Axis of the parent.

[SerializeField] private GameObject _listener;
    [SerializeField] private GameObject _riecever;

    void Update()
    {
        _listener.transform.LookAt(_riecever.transform);
    }
