XS3868 Pin 7 Charge pin? Answered

Hi. I have a XS3868 Bluetooth Audio Module. I found that pin 7 (7th pin on left) is being labelled as Charge. But in some other image,it is labelled as LED. Is it a pin that can light up an led if the battery powering it is getting low? Anyone with experience with XS3868 please tell me...
