Xamarin iOS - Objective - C Binding: No implicit reference conversion between Objecttype and NSObject

I have a Problem with a Xamarin.iOS Objective-C Binding. I'm using Objective Sharpie 3.5.41 to generate the ApiDefinitions and StructsAndEnums. I'm generating an Intent Protocol Definition with Custom Intent Type.

The Problem is that the Object `IntentAppliance` is typed to `INObject` cannot implicitly used as a type for an `INObjectCollection`. The method
```
[Abstract]
[Export ("provideApplianceOptionsCollectionForApplianceSelection:withCompletion:")]
void ProvideApplianceOptionsCollectionForApplianceSelection (ApplianceSelectionIntent intent, Action, NSError> completion);
```
creates the Error
```
ApiDefinitions.cs(150,150): Error CS0311: The type 'IntentBinding.IntentAppliance' cannot be used as type parameter 'ObjectType' in the generic type or method 'INObjectCollection'. There is no implicit reference conversion from 'IntentBinding.IntentAppliance' to 'Foundation.NSObject'.
```

The Definition of the class `IntentApplaince`:
```
[Watch (5,0), NoTV, Mac (10,16), iOS (12,0)]
[BaseType (typeof(INObject))]
interface IntentAppliance
{
// @property (readwrite, copy, nonatomic) NSString * _Nullable id __attribute__((availability(ios, introduced=13.0))) __attribute__((availability(macos, introduced=10.16))) __attribute__((availability(watchos, introduced=6.0)));
//[Watch (6, 0), Mac (10, 16), iOS (13, 0)]
[NullAllowed, Export ("id")]
string Id { get; set; }
}
```

### Steps to Reproduce

1. Create Intent Definition File with Xcode which includes a self designed Type
2. Create a static Objective-C Library from the generated Classes from the Intent Definition File
3. Add Native Reference to the static Library
4. Create ApiDefiniton and StructsAndEnums with Objective Sharpie 3.5.41 with the following Command `sharpie bind --output=. --namespace=IntentBinding -sdk iphoneos$(shell xcrun --show-sdk-platform-version --sdk iphoneos) --scope ../iOS.Native ../iOS.Native/IntentDefintionStaticLib/*.h`

### Expected Behavior
A Generated and compilable `ApiDefinistion.cs` and `StructsAndEnum.cs`
### Actual Behavior
