I can't figure out the wait for seconds command

Im trying to make something spawn every 5 seconds but whenever I do, it just spawns hundreds without waiting, can someone help me out here, there is also a error saying it can’t be in fixed update because " ‘void’ is not an iterator interface type"

my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CoinDropper : MonoBehaviour
{

public GameObject prefab;

// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void FixedUpdate()
{
    Vector2 position = new Vector2(Random.Range(-10f, 10f), Random.Range(3f, 3f));
    Instantiate(prefab, position, Quaternion.identity);
    yield return new WaitForSeconds(5);
}

}

@TCemAlpaydin is correct, the yield return commands must be inside of a Coroutine. Also, the yield return new WaitForSeconds(5); needs to be before the code you want to call after waiting for 5 seconds. This is what that might look like:

void Start()
{
	StartCoroutine(SetRandomPosition(5));
}

private IEnumerator SpawnAfterDelay(float waitTime)
{
	yield return new WaitForSeconds(waitTime);
	Vector2 position = new Vector2(Random.Range(-10f, 10f), Random.Range(3f, 3f));
    Instantiate(prefab, position, Quaternion.identity);
}

This code will wait 5 seconds upon Start, and then instantiate the prefab at the random position.

it needs to be a coroutine for yield return commands to work. Besides this code would have done the same thing after waiting for 5 seconds.
