Implementing Amazon Rekognition and Liveness Check in C# WinForms Application

I am developing a C# WinForms application and seeking guidance on integrating Amazon Rekognition for identity verification, along with a Liveness check. After initiating a session and obtaining the session ID, I am unclear on the process for starting the session in the WinForms environment. Specifically, I need to know whether to send the video frames sequentially or as a whole for the Liveness check and how to handle the verification process after acquiring the session key and before receiving the results. Is there a recommended approach or best practice for this, especially in a WinForms context? I've consulted the documentation but found no WinForms-specific information. Any insights or resources would be greatly appreciated.
