Desconexión de la batería de Samsung Galaxy S8+

The spudger tool has a pointy end and a flat end, it’s not clear which end should be used. Furthermore, the flat end is too wide to insert into the area shown, so the pointy end would seem obvious, but there is no clear indication whether it should be used to push any tabs in the area referenced, which I couldn’t find any, or if you’re meant to just sort of pry it in there until the area pops up, which is what I had to do. Then use the flat end of the spudger to lift it up gently after releasing, or popping the opposite side up as well.
