How can I smooth out 2D object movement?

Hello, I am a VERY new developer, so I apologize if this is a basic question, but I have scoured the site for an answer and cant seem to find the solution.

I am trying to create an enemy script that will have the enemy walk around randomly, which I have sort of accomplished, but he snaps around to each random position instead of smoothly moving to the position. I have tried several iterations with lerp and transform and translate, but nothing seems to work!

Here is the closest I have come so far:

 public class EnemyBehavior : MonoBehaviour {
 
     public float Speed;
     private Rigidbody2D rb2d;
 
     void Start() {
 
         rb2d = GetComponent<Rigidbody2D> ();
         StartCoroutine(Wait());
     }
 
   private IEnumerator Wait() {
             
         float randomX;
         float randomY;
 
         randomX = Random.Range (-1, 2);
         randomY = Random.Range (-1, 2);
 
         Vector2 movement = new Vector2 (randomX, randomY); 
 
         rb2d.MovePosition (rb2d.position + movement * Time.deltaTime * Speed);
 
         yield return new WaitForSeconds(2f);
 
         StartCoroutine(Wait());
 
         }
 
 }

This code will make the enemy move to a new position within 1 tile every 2 seconds. The problem is he just "appears" there and I want it to seem smooth like he is walking.

Any help would be greatly appreciated!

hi, check this it might be helpful :)

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 public class healthManager : MonoBehaviour {
 private Rigidbody2D rb2d;
 void Start() {
     rb2d = GetComponent<Rigidbody2D> ();
     StartCoroutine(Wait());
 }

 private IEnumerator Wait() {
     rb2d.velocity = new Vector2 (UnityEngine.Random.Range(-1,2),UnityEngine.Random.Range(-1,2));
     yield return new WaitForSeconds(2f);
     StartCoroutine(Wait());
 }
 }
