2016 BMW 320I Seats Problems

I have referred to the owner's manual of my vehicle and it does not show me nor indicate how to get access to the trunk from the inside of the vehicle in an emergency situation. I've looked for a seat release latch handle and there is not one. I've researched and contacted BMW experts and they state normally it should have one, other times it may not... I've pulled the middle seat armrest down to expose the plastic access hatch and when I pulled it out of the way, it exposed a metal frame that was in the way and appeared it was part of the backseat metal frame. I've felt around, looked and mentioned this to experts, and they could not explain anything of the sorts other than "normally it should have one, other times it may not...". Ultimately, I find this extremely hazardous, because it is very misleading...
