• originalImplementation is an object that contain functions that have the original implementation for this recipe. They can be used in your functions as a way to use the SuperTokens' default behaviour.
• In the above code snippet, we override the consumeCode function of this recipe. This function will be used to handle the scenario when the user enters an OTP or clicks on a magic link.
