changeNotification.EncryptedContent.DecryptAsync() is always returning error

Hi @PaoloPia

I was trying to implement a subscription to receive notifications the same way that you have done in this solution MSGraphSDK4Subscriptions but I stumbled upon an issue with decrypt the encryptedContent.

Message: Internal.Cryptography.CryptoThrowHelper.WindowsCryptographicException: 'Access denied.'

Code where it raises the issue:
var attachedMessage = await notificationItem.EncryptedContent.DecryptAsync<ChatMessage>((id, thumbprint) => Task.FromResult(certificate));

do you maybe have any clue on where the issue might be.
Appreciate your support.!
