Rear sideglass removal?

I am planning on tinting my windows myself, but will need to pull the rear side glass out to do a decent job. Anyone know how it comes out? Thanks!

on the inside were the 3 black round things are outside there are some covers gently pry them open and there will be a screw there hold the outside round things with something (be carefull not to scratch them) and turn the screw thay will then come out not much to it
