## DeviceCodeGrantHandler Class

Handles the Device Code grant type as defined in RFC 8628\.
This handler validates token requests for the device authorization flow,
checking the device code status and returning tokens when authorized\.

```csharp
public class DeviceCodeGrantHandler : Abblix.Oidc.Server.Endpoints.Token.Grants.IAuthorizationGrantHandler, Abblix.Oidc.Server.Common.Interfaces.IGrantTypeInformer
```
