Leer 100XL Pop Out Side Window Hinge

I have a Leer 100XL with the side pop out side windows and I’m trying to figure out how to detach the hinge from the glass. On my old SUV with pop out rear windows I used to be able to just push in a pin and the hinge would come off of the window letting the pop out window be folded at basically at 90 degree angle allowing more airflow through it when parked. I’m trying to do the same with these side windows on the leer 100xl but just can’t figure out how to detach it, there must be a way since it’s a separate glass piece and would get replaced if broken.
Any help would be appreciated.
