How to implement random movement of Unity objects?

Question

Unity

Objects are generated from one point. There is an end point. The generated objects should come to this point in random directions. If I connect a randomizer, then the generated objects constantly change the X coordinate (Y is always the same), which creates an element of object jitter. How to fix it?

using UnityEngine;

public class WatchAttack : MonoBehaviour
{
    public float Speed;
    public Vector2 Direction;
    public GameObject WatchTarget;
    float XVector;

    [System.Obsolete]
    void FixedUpdate()
    {
        RandomX();
    }

    [System.Obsolete]
    void RandomX()
    {
        XVector = Random.RandomRange(-8, 8f);
        Direction.x = XVector;
        Direction.y = WatchTarget.transform.position.y;
        transform.Translate(Speed * Direction, Space.World);
    }
}
