Aggregate Exception not caught in xunit test cases

I'm querying a third-party SDK with a fully async-await method and SDK returns an AggregateException in a normal scenario. In AggregateException inner exception will be a type of ABCException.

But while mocking the same code in unit test cases with Moq and XUnit it will return ABCException directly.

This is the code part for the catch block:

public async Task<Response> ExecuteAsync(IFunction function)
{
    try
    {
        return await InvockAsync(function, location);
    }
    catch (AggregateException ex)
    {
        ex.Handle(e =>
        {
            if (e is ABCException)
            {
                DoSomething();
            }
        }
    }
    catch (ABCException ex)
    {
        DoSomething();
    }
}

This is the code block for the unit test case:

public async Task UnitTest()
{
    // Arrange
    var mockService = new Mock<IService>();
    mockService.Setup(x => x.InvockAsync(It.IsAny<IFunction>())).ReturnsAsync(new Response());

    var instance = new OtherService(mockService.Object);

    Func<Task> func = async () => await instance.ExecuteAsync(data);

    //Act
    var data = await Assert.ThrowsAsync<AggregateException>(func);

    //Assert
    Assert.IsType<AggregateException>(data);
}

In the above code, a normal call comes AggregateException and unit test cases call comes into ABCException.
