WHAT is it - in the Yaris 2019 LE front grille ?

In front grille of Yaris 2019 LE (black plastic) there are two left/right openings below headlight which are covered with well blending, plastic, removable flaps.
Behind them there is a large threaded socket.

What is it ?

Thanks, Adam

Had it been equipped with them, that is where the fog lights are located.
