metal sticking out next to battery 2022 corolla

[brainii]

Please see the attached photo.

Anyone knows the purpose of the metal part sticking out in the red circle? I thought it was there to help jump start the car, but in the manual the ground point is elsewhere (also the sticking out metal is painted).

 

thanks

The bar is part of the Battery clamp and is used on multiple models some of which have an additional clamp which hooks onto the "metal part" to clamp the Battery down
