Trying to make 2×3 piston door.. how do I turn off the torch on the inside?

I have a piston door as per the picture. I have a button on the other side to get in but I'm having trouble figuring out how to set up a button or pressure plates to get out. I also wish to make the bottom bit cleaner and easier to hide.

I have attempted to use a sticky piston with redstone block pushing down but quasi connectivity messed it up and I wish I could utilize it effectively. and using a slime block on the piston moved some stuff around the build. I am bad at redstone yes but this seems so simple so I thought I could do it on my own but now I'm at my wits end. I'm open to any and all suggestions.
