Hi there!

You can pass a function to the chatbot to check if the client message is valid or not:

const validator = (input) => {
     if (input.length > 3) return true;
     return false
}

<Chatbot messageParser={messageParser} config={config) actionProvider={actionProvider} validator={validator} />
