import SuperTokens from 'supertokens-react-native';
SuperTokens.init({    // ...,    apiDomain: "...",    override: {        functions: (originalImplementation) => {            return {                ...originalImplementation,                doesSessionExist: async function (input) {                    // TODO: some custom logic
                    // or call the default behaviour as show below                    return originalImplementation.doesSessionExist(input);                },                // ...                // TODO: override more functions            }        }    }});

• originalImplementation is an object that contains functions that has the original implementation for this recipe. It can be used in your functions as a way to use the SuperTokens' default behaviour.
• In the above code snippet, we override the doesSessionExist function of this recipe. This means that when another recipe is using this recipe to check if a session exists, it will use your function.
