Question about Xiaomi Air Compressor 2

The Xiaomi Air Compressor 2 has a digital pressure display and a preset pressure function that automatically stops inflation when the desired pressure is reached. However, there is no explicit indication or function that allows air to be released in a controlled manner if too much pressure has been pumped in. Although the operation includes buttons for increasing and decreasing the pressure, these are used to set the target value before inflation, not for targeted deflation after inflation.
