Get all where sub-item is null

Is your feature request related to a problem?

Sorry if this is basic! But I just can´t filter/select by null values. I have looked everywhere. I have tried all kinds of syntax without any luck. I gave this here a go https://chillicream.com/docs/hotchocolate/fetching-data/filtering.

So here I´m getting everything, and you see a Site == null. I would like to get all where Site == null

The solution you'd like

But I would like something like this this

{
devices(where: { site: { any: false} }) {
    nodes{
        id
        machineCode
        site {
                id
                customer {
                    id
                }
                address {
                    city
                }
            }
        hardwareInformation {
            systemVendor
        }
    }
}

Is this possible to day?

Start by reproducing the devices query from the issue and compare it with the Hot Chocolate filtering documentation linked there. Investigate how filtering represents a null related Site, then verify that an equivalent filter returns only devices whose Site is null.
