Improve charging status feedback #9
Description
It is a bit hard to know if the buzzer charging. For both versions of the buzzer, there is a small led on when it is charging (blue led for the Az Delivery ESP32, red led for the Xiao ESP32), but being on the module, we barely see it through the USB hole on the buzzer side.
It would be better to have a led exposed directly on the casing of the Buzzer, or an info on a small screen.
