Okta-Sdk-DotNet: Support for validating security question answer

I am building a custom password reset flow using the Okta-Sdk-DotNet and cannot see a way to verify the users security question answer and set their new password via the SDK. I can do this via the OKTA api using the following endpoint:

[Post] {AuthServer}/api/v1/users/{userId}/credentials/forgot_password
With the body:
{
“password” : {
“value”: “newPasswordValue”
},
“recovery_question” : {
“answer” : “Users answer”
}
}

but cannot find a way to do this in the SDK. Can you confirm if this is possible?

maybe you need that -> https://github.com/okta/okta-auth-dotnet
