Here is my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using GoogleMobileAds;
using GoogleMobileAds.Api;

public class GoogleAdMobADS : MonoBehaviour {
public bool pr;
// Use this for initialization
private RewardBasedVideoAd rewardBasedVideo;

public void Start()
{
    pr = false;
    // Get singleton reward based video ad reference.
    //this.rewardBasedVideo = RewardBasedVideoAd.Instance;
    // Get singleton reward based video ad reference.
    this.rewardBasedVideo = RewardBasedVideoAd.Instance;
    
    this.RequestRewardedVideo();
    
}

// Update is called once per frame
void Update () {
    if (rewardBasedVideo.IsLoaded())
    {
        pr=true;
        rewardBasedVideo.Show();
    }

}
private void RequestRewardedVideo()
{
    //ca-app-pub-3940256099942544/5224354917
    string adUnitId = "ca-app-pub-3940256099942544/5224354917";
    // Create an empty ad request.
    AdRequest request = new AdRequest.Builder().Build();
    // Load the rewarded video ad with the request.
    rewardBasedVideo.LoadAd(request, adUnitId);
}

}

I wrote this code in the script and added that script to empty game object on the scene. After that I made game and tested the game on Android device, but before that I had tested game in unity editor too. Ads are not showing. Thank you in advance!

IEnumerator WaitVideoToLoad() {

                while (!_rewardBasedVideo.IsLoaded()) {
                    Debug.Log("Wait video 1s");
                    yield return new WaitForSeconds(1);
                }
    
              
                rewardBasedVideo.Show();
}

But this wont work. You need to subscribe to onAdLoaded event:

 this.rewardBasedVideo.OnAdLoaded += this.HandleRewardBasedVideoLoaded;


 
 public void HandleRewardBasedVideoLoaded(object sender, EventArgs args)
    {
       rewardBasedVideo.Show();
}
