so i noticed that the FC has the ability to buzz when the vbatt is too low. is it at all possible to access that buzzer to be used on for example Aux2 as a lost model buzzer? is it something that will require CLI coding? is it just not possible? i have tried setting the channel switch in the modes menu of betaflight, but it just turns on the Red board LED. much thanks to anyone who can help me out on this.
