2017 honda accord third brake light does not work. no mention of the issue online

2017acrd

i have scoured the internet but can't find anything about this issue (except that the bulb is a led assembly). does anyone have any insight on what the issue might be in the third brake light does not light up when the brake is depressed but the other brake lights do? i looked at the fuses but i think that is shared with the other brake lights. thanks in advance.
