I am currently building a react app with @humeai/voice-react The problem is that everything is on the "client side" This makes it difficult to build secure apps. For example, I want that when the user clicks on the call button, a modal appears if they don't have enough credits. Since everything is on the "client side", I am not sure it is possible to build this feature securely. Another example, I want to decrease the credits by 1 for every minute in the call. Same problem, everything that gives me information about the length of the call can be manipulated on the client side. Is there a work around?
