Screen pressing on flex cable

I tried replacing the front speaker mesh and i had to open my display for that. i opened my display but i dont know if i should glue it back on because i have the battery still inside and the flex cable is making some kind of pressure so when i press on the display it presses on the flex cable

what should i do now? should i disassemble the battery to get to the flex cable? if yes, how do i glue the battery back on?
