Is there any option for Mock EncryptAsync() in Azure.Security.KeyVault.Keys.Cryptography

I am trying to mock the functionality of the EncryptAsync method in Azure.Security.KeyVault.Keys.Cryptography.CryptographyClient.

This is the method I am trying to cover in my unit test.

public KeyVaultClientWrapper(KeyClient keyClient, SecretClient secretClient, CryptographyClient cryptographyClient)
    {
        _keyClient = keyClient;
        _cryptographyClient = cryptographyClient;
        _secretClient = secretClient;
    }

    public async Task<EncryptResult> EncryptAsync(string keyName, string algorithm, byte[] plainText, CancellationToken cancellationToken = default)
    {
        return await _cryptographyClient.EncryptAsync(algorithm, plainText, cancellationToken);
    }

I'm unable to create new object of EncryptResult that needs to returned from the mock EncryptAsync method because there is no Set for EncryptResult

var _mockKeyVaultClient = new Mock<IKeyVaultClient>();
    var _mockCryptoClient = new Mock<CryptographyClient>();
    mockCryptoClient
            .Setup(client => client.EncryptAsync(EncryptionAlgorithm.AES, plaintext, default))
            .ReturnsAsync(new EncryptResult { Ciphertext = ciphertext });

How can I change this mock class so that EncryptAsync returns a valid EncryptResult object while running the test method?

Is there any alternate option for testing the same?
