1997 Nissan Altima How to replace brake light in 1997 nissa

I need to replace the brake ligt (center one on top of the back seat) in my 97 nissan altima.
It doesn't look like you can access it through the trunk.
I tried pulling the back seat up. But it seems to be a little more complicated than I thought and I wanted to first make sure this is the correct meathod.
Thank you for your answer.
