    Hi, I’m a software architect in my company and we are evaluating alternative in the market to extend on ouf our SaaS solutions to include video call features along, video recording of the call. From your website it seems that this feature are part of the MirrorFly services, but in the Docs & API page we could only find information regarding client-side libraries for Android/iOS/Javascript, and nothing regarding the video recording part, nor any kind of server side SDK or API documentation. It is also unclear if the MirrorFly service is designed to be used only as a client-side enablement, or if it can suite our scenario where we also need to interact with our “server side” code that should for instance force the recording, and retrieve the recorded media. Our current understanding is that MirrorFly is not suited for our use case.
