Architecture test using NetArchTest gives false result when trying to assert sealed class fitness rule

I'm writing Architecture Fitness Test using NetArchTest and I'm trying to Assert if all of my Request Class are sealed using the below test,

[Fact]
public void Should_Have_Request_To_Be_Sealed()
{
    var result =
        Types.InAssembly(typeof(ApplicationServiceRegistration).Assembly)
            .That()
            .AreClasses()
            .And()
            .Inherit(typeof(IRequest))
            .Should()
            .BeSealed()
            .GetResult();

    Assert.True(result.IsSuccessful);
}

Here are the examples of my Request Class,

public class CreateCategoryCommand : IRequest<Result<CategoryDto, BaseError>>
{
    public string Name { get; set; } = string.Empty;
    public string? Code { get; set; }
}

public class CreateClientCommand : IRequest<Result<ClientDto, BaseError>>
{
    public string Name { get; set; } = string.Empty;
}

As we can see, the Request Class are not sealed, but still the test gets passed.

Am I missing anything? Please assist.

I figured out. I should use ImplementInterface instead of Inherit as shown below,

[Fact]
public void Should_Have_Request_To_Be_Sealed()
{
    var result =
        Types.InAssembly(typeof(ApplicationServiceRegistration).Assembly)
            .That()
            .AreClasses()
            .And()
            .ImplementInterface(typeof(IRequest)) <-- Changed here
            .Should()
            .BeSealed()
            .GetResult();

    Assert.True(result.IsSuccessful);
}
