Specialized construction equipment has a particularly complex set of instructions for use and error handling. The current Hotline channel is facing difficulties due to the lack of images or visual descriptions from customers. The company needs a more intuitive connection channel with customers to provide the fastest experience - the most convenient when using as well as handling errors, to ensure the safety of users.
