I tried to do so with https://github.com/ise621/database/blob/develop/backend/src/GraphQl/DataX/DataFilterTypeBase.cs#L33-L56 but failed. With this approach I get the following runtime error

System.NullReferenceException: Object reference not set to an instance of an object.

Ask the developers of HotChocolate to support not in addition to and and or!
