How to select nested objects using Gridify.Elasticsearch?

[P9avel]

Hi. i am saved in ES object
{
"checkoutId": "743721325",
"uniqueId": "d832d4e5-a480-4d13-ab0d-0f221ff6f1e7",
"checkoutCreatedAt": "0001-01-01T00:00:00",
"products": [
{
"productId": "234356",
"productName": "Test product"
}
]
}

I am tried query products.productId = 234356, but recived NotSupportedException
My simpled class here
public sealed record Checkout
{
public Product[]? Products { get; init; }
}

public sealed record Product
{
public string ProductId { get; init; }
public string ProductName { get; init; }
}

But in ES all works
