I need to unit test my hangifre recurring job with NSubstitute, my service class as follows, now I need to run test for it.

public class ItemService : IItemService, IJobConfigurationService
 {
     private readonly IItemRepository itemRepository;
     private readonly ISettingRepository settingRepository;
     private readonly ILogger<ItemService> logger;

     public ItemService(IItemRepository itemRepository
         ,ISettingRepository settingRepository
         ,ILogger<ItemService> logger)
     {
         this.itemRepository = itemRepository;
         this.settingRepository = settingRepository;
         this.logger = logger;
     }

     public void ConfigureJob(string cronExpression)
     {
         RecurringJob.AddOrUpdate("PermanentlyDeleteItemsAsync", () =>
             PermanentlyDeleteItemsAsync(), cronExpression);
     }

     public async Task PermanentlyDeleteItemsAsync()
     {
         //some logic here
     }
 }

I tried my unit test method something like this,

[Fact]
public async Task ConfigureJob_AddsOrUpdateRecurringJobAsync()
{
    // Arrange
    var itemRepository = Substitute.For<IItemRepository>();
    var settingRepository = Substitute.For<ISettingRepository>();
    var logger = Substitute.For<ILogger<ItemService>>();
    var mockRecurringJobManager = Substitute.For<IRecurringJobManager>();

    var service = new ItemService(itemRepository, settingRepository, logger);
    string cronExpression = "0 * * * *"; // Every hour

    // Act
    service.ConfigureJob(cronExpression);

    // Assert
    mockRecurringJobManager.Received().AddOrUpdate(Arg.Any<string>(),
        () => service.PermanentlyDeleteItemsAsync(), cronExpression);
}

This didn’t work and is this correct way to test it? because I’m new to Hangfire
