UMIDIGI G Notification LED

ionici

Hello everyone!
I bought recently a phone UMIDIGI G, but the function "LED notification" does not work for him.
On the Bangood site, where I bought it writes that has this function but to me does not work. So does anyone know if this model has this functionality or not? And if he has this function How can I activate it?
